Version: 1.4.4 SVN (using KDE KDE 3.5.5) Installed from: SuSE RPMs Compiler: gcc version 4.0.2 20050901 (prerelease) (SUSE Linux) OS: Linux Steps to reproduce: 1.) Start Amarok 2.) Close Amarok while it is still loading the playlist -> crash BT: http://amarok.pastebin.ca/222426 This is also a dataloss bug: the playlist is cut to only a few songs after reproducing the problem a few times.
