Sentry Crash Report:

Description Valerian 2009-10-16 06:13:48 UTC 
Application that crashed: amarok
Version of the application: 2.2.0
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.26-2-amd64 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
(not often) crash when manually pass to the next track.

I was jast listening music.
On attempt to skip a bad track everything freeze for a second then Amarok die.
This happend thrice during 9 hours (now, there were cases earlier, but not three in a row).
Of course music was different.
I was using constant playlist (if this important).
Do not know what kind of information can be userful...

(C. Assistant say that debugging information is bad. I can install those ridiculusly big -dbg pakage and i alredy installed amarok package (for example), maybe anything else. jast name them.)

You want to get rid of the ?? and the "value optimized out" to turn this into a better backtrace. For an even better one, it will have line numbers at the end of each line. 

Install the debug packages for xine and/or xine-pulseaudio. (libxine1-dbg, libxine1-misc-plugins perhaps)

But this is actually a xine or pulseaudio bug, and should be filed against them. 

Thanks!
Comment 2 Dario Andres 2009-12-27 22:00:53 UTC 
The PulseAudio integration was improved a bit for the new version Phonon.
