rhythmbox crashes in three seconds after startup

[Robert Roth]

Binary package hint: rhythmbox

After starting rhythmbox, the main interface appears, but after max. three seconds it disappears ... crash at maximum. This happens always, no matter where do I start rhythmbox from (sound menu, applications menu, terminal).
When starting from terminal, this is all I see:

(rhythmbox:7777): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed

I have the same bug on the same version of Ubuntu (Maverick i386 image dated 26 August, kernel 2.6.35-19). Happens every time.

[jaduncan (jaduncan)]

Confirmed here too.

[paulk3n (pderendinger)]

Confirmed here too.
Maverick Alpha 3 amd64

Thank you taking the time to report this bug and helping to make Ubuntu better. Please try to obtain a backtrace manually following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. This will greatly help us in tracking down your problem.

We have a couple of crashes on startup with latest rhythmbox so this could be a duplicate. please obtain a backtrace to determine that, thanks in advance.

Affects me as well

The GDB console crashes and doesn't accept any input after rythmbox freezes. Pressing Ctrl-C does not do anything. Ctrl-Z works. However, cannot type the backtrace full statement or anything after that, so cannot take a backtrace.

[Brian John (brianji03)]

I just installed the daily build of Maverick on my computer (i386)
I am witnessing the same bug.

[Alexander Usyskin (sanniu)]

Have the same behavior.

This is affecting me as well (Ubuntu Maverick). I've attached a complete backtrace.

[Jason J. Herne (hernejj)]

I have this problem as well.

Since this is reproducible my multiple people and the requested back traces have been supplied I believe "Confirmed" is the appropriate status for this one :)

[Jason J. Herne (hernejj)]

I noticed the complete back trace posted above was collected without some of the debugging symbols. Here is one that has all the function addresses symbols resolved.

[Jason J. Herne (hernejj)]

Another interesting note.

I erased my rhythmbox configuration directory and copied my old one form my Karmic partition and it started right up! :)

rm -rf ~/.local/share/rhythmbox/
cp -a /media/karmic_OLD/.local/share/rhythmbox/ ~/.local/share/

So this my be a viable workaround for others having this problem.

[jolo (joop-loep)]

@Jason J. Herne Thanks for the workaround. Also here the workaround seems to work. Only it is not necessary to remove the ~/.local/share/rhythmbox/ directory. I did only copied the playlists.xml from Ubuntu 10.04 to Maverick' ~/.local/share/rhythmbox/ directory.
