rhythmbox, dead-lock between songs

[Fabien Tassin]

Binary package hint: rhythmbox

On intrepid, rhythmbox recently started to stop playing between songs (some, not all). At the end of a song, the next one is not played, the CPU jumps and stays like that. When I click next, the UI freezes.
It happens very frequently, forcing me to kill rhythmbox. I use x-fading between songs.

Under gdb, if I break during the freeze, i see a dead-lock..
Assigning to rhythmbox but it could be gstreamer's fault. Feel free to re-assign.

Could you try if that's still an issue using the current versions and report the bug to GNOME?

[Gert van Dijk (gertvdijk)]

Last night I got this same issue. In Hardy it was more often though and only when enabling crossfading between songs, now also when doing a fast forward in a song.

[Steve Beattie (sbeattie)]

Gert, are you claiming you had this problem in Hardy as well?

Fabien, are you still seeing this issue?

[Gert van Dijk (gertvdijk)]

It was present for me in Hardy in particular and I kept having this problem a few weeks in Intrepid. It was about 30 songs (random/shuffle from library) it would last for the first freeze to occur.
Now, with intrepid-updates, -proposed and -backports enabled I haven't had this problem in weeks.

[Steve Beattie (sbeattie)]

Fabien, are you still having this issue? If not, can you mark this bug as Fix Released? Thanks.

May be relevant information:
before rhytmbox frozen, i pause'd it, made call with skype, while speaking in skype, tryed to start playing music, what failed, but without UI freezing, later after i ended to speak in skype, i pressed FN+F9(continue music playing), it didn't continue music playing, than i opened UI by clicking tray icon and found that it is frozen.

Thank you for taking the time to report this bug and helping to make Ubuntu better. A new version of GStreamer is available in both Lucid and Maverick and we are wondering if this is still reproducible in any of those versions, May you please test and give us of feedback about it? Thanks in advance.
