Comment 1 Mark Kretschmann 2009-05-24 21:48:44 UTC
It's evident from the backtrace that the crash happened within the X11 graphics stack. So it's not in Amarok code.

See this line for proof:

#4  0x00007f187f3215f7 in XGetImage () from /usr/lib/libX11.so.6


Sorry, but there isn't anything we could do about this. It may be a problem with your graphics driver.

It is related to Xine-FFMPEG(libavcodec)

Bug 192890 / bug 188814 could be related. May be bug 187551 too

Are you using PulseAudio ? 

Can you reproduce the crash at will ? If you do, can you try uninstalling the ffmpeg extension of xine ?

Thanks

>Are you using PulseAudio ? 

No, I have wiped it at first possibility. 


>Can you reproduce the crash at will ?

Will try a bit lately.
Comment 4 Sergei Andreev 2009-08-16 16:00:29 UTC
Seems to be really fixed.
