Exaile doen't start after last upgrade

I have this bug in Ubuntu 11.04(GNOME).

Same issue here. Fresh Xubuntu 11.04 amd64 alpha2 install with latest updates (until 09.02.2011).

I don't know if this is an upstream bug, but I'm reporting there as well to get it looked at before 0.3.2.1.

I just reproduced this with rev 3793 of lp:exaile. The traceback is essentially the same, some line numbers have changed:

Traceback (most recent call last):
  File "/home/andrew/usr/lib/exaile/exaile.py", line 61, in <module>
    main()
  File "/home/andrew/usr/lib/exaile/exaile.py", line 58, in main
    exaile = main.Exaile()
  File "/home/andrew/usr/lib/exaile/xl/main.py", line 118, in __init__
    self.__init()
  File "/home/andrew/usr/lib/exaile/xl/main.py", line 248, in __init
    self.gui = xlgui.Main(self)

    panel.connect('append-items', lambda panel, items, sort=sort:
TypeError: <PlaylistsPanel object at 0xaa3939c (xlgui+panel+playlists+PlaylistsPanel at 0xabcf390)>: unknown signal name: append-items

I'm not getting this bug in ArchLinux (0.3.2 and trunk), and reportedly it's fine in Fedora as well (0.3.2). Yesterday I tried stock Ubuntu Netbook and it worked (trunk).

So... not sure; issue with the specific PyGObject version maybe? Are you able to downgrade pygobject to see if that's the problem?

Versions in natty:

python-gobject:
  Installed: 2.27.0+git20110131-0ubuntu6
  Candidate: 2.27.0+git20110131-0ubuntu6

python:
  Installed: 2.7.1-0ubuntu5
  Candidate: 2.7.1-0ubuntu5

For reference, the current arch versions (which do NOT reproduce the problem) are:

pygobject: 2.26.0-2
python2: 2.7.1-4

So it seems possible this is a bug in the prerelease version of (py)gobject that natty is using.

I can't reproduce on Fedora and I'm using:

pygobject: 2.21.5-3
python2: 2.7.8

As Aren said, probably this is a bug in prerelease version of (py)gobject.

I suspect this has something to do with how we implement the PlaylistsPanel class: it inherits from 2 GObject classes, and the append-items signal comes from the second parent.

IIRC GObject itself doesn't support multiple inheritance, so I'm absolutely confused why this works/worked.

I'm attaching a test case that can be used to check if this is indeed the problem. If it is, we'll have to ask the (Py)GObject people whether it's intended. Can anyone on natty run this and see whether you get an error (it prints "OK" if everything works)?

On Maverick:

$ python gobject-multi-inherit.py
OK

On Natty:

$ python gobject-multi-inherit.py
Traceback (most recent call last):
  File "gobject-multi-inherit.py", line 15, in <module>
    c.connect('b', lambda *x: None)
TypeError: <C object at 0xb754989c (__main__+C at 0x8834200)>: unknown
signal name: b

I'm posting a question in the PyGTK mailing list, asking whether the error is expected.
http://www.daa.com.au/pipermail/pygtk/2011-February/019394.html

So far no responses in the pygtk list.

Andrew / others, can you test the 2 new attached files (#2 and #3) on natty? They are slightly modified versions of the previous attachment; just want to see if one of them can be used as a workaround.

Exaile is not working for me after a fresh install of Xubuntu Natty Alpha 2; here's some debug info:

Thanks everyone who tested. I've committed something resembling #3, but please check if it works. The patch is at http://bazaar.launchpad.net/~exaile-devel/exaile/0.3.2.x/diff/3452

By the way, this is the last bug blocking 0.3.2.1. Once we get a confirmation of the fix, we should be good for a release.

The patch you supplied works for me on natty. Thx

This bug was fixed in the package exaile - 0.3.2.1-0buntu1
