rhythmbox hangs after a few days (too many threads?)

[Mike Coleman]

Binary package hint: rhythmbox

I've noticed that recent versions rhythmbox hang after they've been running a few days (at least for me). I tried attaching to a hung program with gdb. I did notice that there were over 500 threads, which seems odd, but I have no idea what else to look for.

Thanks for your bug report. Please try to obtain a backtrace of the hang http://wiki.ubuntu.com/DebuggingProgramCrash and attach the file to the bug report. This will greatly help us in tracking down your problem.

Here's a backtrace. It's a hang, but I'm not sure it's exactly the same hang (the notable difference is that in this case, the app won't repaint and the CPU is spinning, whereas before I think it was repainting and sleeping--maybe that's not a meaningful difference, though). As before there are hundreds of threads.

Not sure whether there are enough symbols in here to be useful or not. Rhythmbox seems to link to a million zillion libraries, and I have no idea of how to pull in all of the necessary lib*-dbg packages without adding them one by one, which I don't wish to do.

One further comment, just by looking at the output of 'ps auxwwm', I can see that rhythmbox is starting a new thread every couple of minutes more or less. This almost certainly coincides with the start of each new song. So the bug would seem to be that these threads are not correctly being terminated.

[Dave Gilbert (ubuntu-treblig)]

OK, I've just seen this as well - it's leaking a task and two fd's on each song and eventually falls over.

Christophe Fergeau has marked the GNOME bug as a dupe with
http://bugzilla.gnome.org/show_bug.cgi?id=567746

that got fixed last month.

It would be good to get that fix into Ubuntu.

the bug is fixed in 0.11.99.1 in jaunty now

[Dave Gilbert (ubuntu-treblig)]

I can confirm the version in Jaunty is fine as of today.
