Description Victor Gavrish 2009-12-21 07:15:19 UTC
Version:           2.2.1-0ubuntu1~karmic1~ppa1 (using KDE 4.3.4)
OS:                Linux
Installed from:    Ubuntu Packages

It inevitably happens whenever I start switching tracks really quickly. Like, starting another track before the first even started to play.

With amarok --debug it says in the end:

KCrash: Application 'amarok' crashing...
sock_file=/home/victor/.kde/socket-victor-laptop/kdeinit4__0
Assertion 'pa_close(fds[0]) == 0' failed at pulsecore/core-util.c:2165, function pa_close_pipe(). Aborting.
Comment 1 Myriam Schweingruber 2009-12-21 10:15:59 UTC
First of all, if you are not using Ubuntu, but Kubuntu, you should not be using Pulseaudio.

Then we need a proper backtrace. If you can reproduce this bug, please check here on how to get a valid backtrace:

http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

Please also try starting Amarok from a konsole with the following options:

amarok -d --nofork

it can sometimes get better results once the debugging packages are installed.

Since you are using Kubuntu, you will need amarok-dbg and phonon-dbg at least, ideally you should also have kdelibs5-dbg, libqt4-dbg and  libglib2.0-0-dbg. That should cover most of the crashes.

Comment 3 Victor Gavrish 2009-12-21 15:50:12 UTC
Hi! First of all, I'm not sure if I'm using Ubuntu or Kubuntu. It was originally installed as Ubuntu, but later I installed the kubuntu-desktop package and am now using KDE.

Second, I think you should know I'm using this PPA:
https://launchpad.net/~kubuntu-ppa/+archive/ppa

Finally, I'm attaching the backtrace (with all the above packages installed :) )
