This affects gutsy btw

Here it is in all standard bitrates between 32k and 192k: http://mihd.net/50slxd

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

I think the attached .crash is the relevant backtrace. I have'nt installed rhythmbox-dbgsym, but I don't need it if i can get the .crash anyway do I?

I've also realised that rhythmbox -d says this when it crashes:
(20:51:31) [0x80fa408] [check-imperfect] rb-player-gst-xfade.c:1523: file:///home/alec/Music/bitratetest/96.mp3: imperfect-timestamp, prev-timestamp=(guint64)1439727891, prev-duration=(guint64)36009070, prev-offset=(guint64)63492, prev-offset-end=(guint64)65080, cur-timestamp=(guint64)2340000000, cur-duration=(guint64)35736961, cur-offset=(guint64)103194, cur-offset-end=(guint64)104770

Segmentation fault (core dumped)

And I've also found out that it only happens with xfade backend. With xfade disabled, it works fine.

What do you call "xfade backend"? How do you active it?

I mean crossfade. Go to Preferences in the Edit menu and then go to the Playback tab. Tick the "Enable crossfading effects" checkbox, and move the slider to 0 seconds. Make sure crossfade between songs in the same album is unchecked. (0 second crossfade=gapless playback. That's what I use it for.) Restart rhythmbox and then try and seek in a 96kbit mp3. (Once you've finished this, you'll probably want to disable crossfade again, as it seems to me that there are quite a lot of other problems with it, eg inability ot play m4a/aac).

Ah I've just realised that backtrace is completely different to the .crash file.... So the backtrace is attached.

Could you install gstreamer0.10-plugins-base-dbg libglib2.0-0-dbg rhythmbox-dbg and get a new backtrace?

Here it is. The only difference from what you asked for is I used rhythmbox-dbgsym rather than rhythmbox-dbg, because aptitude said no candidate version found for -dbg. I hope thats ok :)

looks like you didn't type "thread apply all bt" correctly, could you try again?

Ok the symptoms have changed. It doesn't make it actually crash anymore so I cant get a backtrace.
Usually you can skip once, or perhaps a few times, but then when you try to skip again, either the slider will carry on moving but the song will not play or the slider will not move and the song wont play. It will say in the properties "Internal data flow error"
Often if you start another song playing, then switch back to the song, the same thing will happen again. However, sometimes it will just freeze and make you kill it, but it will never actually crash.

the bug is not clear, maybe it should be closed and a new one opened

Agreed, closing it for now, feel free to open a new one.
