Description Sebastian Insua-Summerhays 2010-01-14 14:54:24 UTC

Application that crashed: amarok
Version of the application: 2.2.2
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.32-ARCH i686

What I was doing when the application crashed:
Updated amarok using pacman on Arch Linux. On next run it started to search for music files on my computer as it normally does, and then crashed.

I can replicate it by starting Amarok again. Every single time it crashes while scanning.

I'm happy to provide more information if you have any questions...

Comment 1 Myriam Schweingruber 2010-01-14 14:59:01 UTC

Please type the following three commands in a konsole, in that order:

  export QT_NO_GLIB=1
  export MALLOC_CHECK_=
  amarok -d --nofork
  
If this solves the problem, then it is the glibc bug 196207. You should make sure to have a patched glibc version, then.

Comment 2 Sebastian Insua-Summerhays 2010-01-14 15:01:43 UTC

It started working again. I've no idea why... :/

After having used the commands I told you or just like this?
