Description Frederik Himpe 2006-07-26 22:06:50 UTC 
Version:           1.4.4 (using KDE KDE 3.5.4)
Installed from:    Mandriva RPMs
Compiler:          gcc 4.0.1 
OS:                Linux

I'm using amarok 1.4.1 on Mandriva Cooker x86_64 with xine 1.1.2 and alsa output plugin.

When quickly switching songs, for example by several times quickly quicking the "next track" button, or by double clicking quickly several times on different songs in the playlist window, I can easily reproduce a crash. I experienced this crash in normal real use situations before, just by skipping several songs.

Comment 1 Martin Aumueller 2006-07-27 01:06:10 UTC 
This smells quite similar as bug #115827. BTW, Amarok 1.4.2 should have improved quite a bit wrt the switching problem.
