[precise] kupfer does not launch

Status changed to 'Confirmed' because the bug affects multiple users.

Can confirm I am seeing the same on an upgraded system from 11.10.

I have this bug in 11.10 as well.

Apologies - I had Calibre's PPA installed (https://launchpad.net/~n-muench/+archive/calibre), which has an updated python-qt4 in it - which I believe is backported from Precise - and causes this error.

I would love a quick workaround for this bug (as I love kupfer). Happy to muck around in the python code.

I attempted to replace all occurances of "import gobject" to "from gi.repository import GObject" as the error stated, but that didn't solve the issue.

Had the same problem on 11.10 as well. It has appeared once I've upgraded packages using Calibre PPA as Mark mentioned - but the source of the problem was python-dbus package (Kupfer shouldn't be affected by python-qt4 since it uses GTK). Once I've downgraded python-dbus from v1.0.0 to Oneiric's v0.84, Kupfer started to work.
Therefore I think you should take a look at python-dbus compatibility.

Jan is correct, downgrading python-dbus to 0.84 worked for me too.

It's been a long time since I tried porting Kupfer to gi (previsouly it stalled on porting gtk styles). It's a big project and not something I'm able to work on at the moment.

Please test latest git http://git.gnome.org/browse/kupfer/ where I've copied the very small file gobject_service.py from dbus-python into kupfer. It seems to work fine on my virtualbox of ubuntu 12.04 :-) the patch also seems to apply to version 206.

this commit: http://git.gnome.org/browse/kupfer/commit/?id=a259639a80f9381d7bf7182863f9832b6676b20f

I can confirm that the fix works.

#10 fixes it, thx :)

Help me understand: If a fix was committed and released on the 26th, why is it not available in the repositories now?

Luke, I'm the upstream maintainer and I released a new fixed version. This bug is also tracked for the kupfer package in ubuntu, and I don't influence that.

Thanks Ulrik! I've been really missing kupfer since I upgraded to precise. Now to see how to get it updated in the repos...

Thanks everyone for your work on this.

I took the liberty of fixing some things in the debdiff in comment 16:
 - ran 'update-maintainer' to satisfy https://wiki.ubuntu.com/DebianMaintainerField
 - re-indented some of the changelog entry bits (please wrap at 80 chars per line)
 - applied the patch from git without modifications (the patch in the debdiff was reindented
   which made python unhappy - the resulting package did not even install)

I just uploaded the fix and it will sit in the review queue of the archive admins / release team.

This bug was fixed in the package kupfer - 0+v206+dfsg-1ubuntu1

---------------
kupfer (0+v206+dfsg-1ubuntu1) precise; urgency=low

  * kupfer/dbuscompat.py
    - copied gobject_service.py verbatim from dbus-python version 0.84.0 to
      kupfer/dbuscompat.py (LP: #921829)
