software-properties-kde does not start, (QtCore Error)

This is affecting other apps requiring the same dependencies (e.g. Eric4).

AFAICS it also affects plasmoids written in Python.

I have 2 installations of Karmic, on 2 different laptops. One 32bit (does not see this bug), and one amd64 (sees this bug)

See comments reporting the same error.

As of today, I don't see the bug anymore, software-properties-kde is launching and working properly.

It should probably be marked as invalid or fixed commited, I don't know which is the 'cleaner' solution.

On my fully updated Karmic I still see the bug on amd64

Hi (sorry for my bad english)

same problem on kubuntu 9.04 under KDE 4.3.1 and QT 4.5.2.

under konsole :

jaja@quadcore:~$ kdesudo software-properties-kde

Traceback (most recent call last):
  File "/usr/bin/software-properties-kde", line 114, in <module>
    app = SoftwarePropertiesKDE(datadir=data_dir, options=options, file=file, attachWinID=attachWinID)

jajaX, different problem (I would actually think that translation-binary-incompability is at fault, not much that can be done there).

Everyone else:
a) is this issue still valid?
b) does sudo apt-get install python-qt4 --reinstall help?
c) what does ls -la /usr/lib/pyshared/python2.5/PyQt4/QtCore.so spit out?

My case, with my fully updated Karmic amd64:

a) yes
b) no
c) yves@viking:~$ ls -la /usr/lib/pyshared/python2.5/PyQt4/QtCore.so
-rw-r--r-- 1 root root 1770368 2009-07-16 02:04 /usr/lib/pyshared/python2.5/PyQt4/QtCore.so

btw I seem to use python2.6, and the file exists for that version of python as well:
-rw-r--r-- 1 root root 1.7M 2009-07-16 02:04 /usr/lib/pyshared/python2.6/PyQt4/QtCore.so

Hi !

a) yes
b) no
c) ls -la /usr/lib/pyshared/python2.5/PyQt4/QtCore.so
ls: ne peut accéder /usr/lib/pyshared/python2.5/PyQt4/QtCore.so: Aucun fichier ou dossier de ce type

=> no files for me.

whoops, I meant ls -la /usr/lib/pyshared/python2.6/PyQt4/QtCore.so

sorry :S

ls -la /usr/lib/pyshared/python2.6/PyQt4/QtCore.so
ls: ne peut accéder /usr/lib/pyshared/python2.6/PyQt4/QtCore.so: Aucun fichier ou dossier de ce type

same thing.

it's normal ?

Not normal no.

What happens when you download
https://edge.launchpad.net/ubuntu/+source/python-qt4/4.5.2-0ubuntu1/+build/1120304/+files/python-qt4_4.5.2-0ubuntu1_amd64.deb
and install that manually?

I use kubuntu 32 bits ;)

Hi !

same result on other computer (for python 2.5 or 2.6) but window "SoftwareProperties" works fine.

other computer use kubuntu 9.04 (32 bits) too.

Just upgraded to karmic from jaunty and have the same problem:

Python 2.6.2+ (release26-maint, Sep 9 2009, 22:58:56)
[GCC 4.4.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import PyQt4
>>> dir(PyQt4)
['__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__']
>>>

I am running Kubuntu 64-bits, all the latest packages are installed.

ls -la /usr/lib/pyshared/python2.6/PyQt4/QtCore.so prints:
-rw-r--r-- 1 root root 1770472 2009-07-16 02:04 /usr/lib/pyshared/python2.6/PyQt4/QtCore.so

I spent some more time trying to figure out why there seems to be nothing in the PyQt4 module and found this:
https://bugs.launchpad.net/ubuntu/+source/python-qt4/+bug/419786

Is it possibly related?

apt-cache search python-qt4-common does list the package, but it isn't installable.

Ok, I fixed the problem. It turned out that I had in fact python-qt4-common installed (which seems to only exist in jaunty), and it wasn't that I needed it, but that it somehow interfered with the karmic packages. So, after doing:

sudo apt-get remove python-qt4-common

everything worked again:

Python 2.6.2+ (release26-maint, Sep 9 2009, 22:58:56)
[GCC 4.4.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from PyQt4 import QtCore
>>> dir(QtCore)
['PYQT_VERSION', 'PYQT_VERSION_STR', 'QAbstractEventDispatcher', 'QAbstractFileEngine', '
...]
>>>

(btw. my first example was actually wrong it seems, but software-notifier-kde and software-properties-kde did exit with the error message mentioned in this bug report. )

I can confirm that what Andreas says works for me as well, on amd64.

I cherry-picked the fix from Debian that should resolve this. Debdiff attached.

This bug was fixed in the package python-qt4 - 4.5.2-0ubuntu2

---------------
python-qt4 (4.5.2-0ubuntu2) karmic; urgency=low

  * debian/control:
    - Add conflicts on python-qt4-common, as per Debian change
      to ensure its removed on upgrades. (LP: #407418)

Have the same problem running Jaunty amd64. After removing python-qt4-common, and then running software-properties-kde, I now get a segmentation fault.

I have now python-qt4 (4.5.4-0ubuntu1) installed.

Any ideas?

Same problem. Kubuntu 10.04 with KDE 4.4.2. The version of python-qt4 is 4.72.

Hi Harald,
Why did you revert the status of this bug? Shall I open a new bug instead?

By the way, my Kubuntu is 64-bit and I don't have python-qt4-common (checked with "aptitude search python-qt4-common").

Open a new bug. This one is fixed.

Hi Scott,

Got it.
