This looks related to bug 211275. Thanks It really does look exactly like bug 211275. However, that bug is marked RESOLVED UPSTREAM, and if that were the case, then I shouldn't be experiencing it. So it should be reopened or at least re-looked at. Unfortunately, it doesn't say how it was resolved or what was the bottomline problem (was it that piece of code or Qt?). If anybody can explain it to me, maybe I can run some better tests. UPSTREAM means that the bug was caused by some of the used libraries, in that case Qt... but I'm not an Amarok developer to tell if the issue was investigated or if it is going to be forwarded to Qt bugtracker. Regards No, this is probably something different, please read up here: http://www.purinchu.net/wp/2009/11/16/malloc_check_-crashes/ If that's really it, it would be a bug in glibc, which is upstream. Please read up on this blog article, and check if the glibc issue might affect you. Thanks. Very interesting. The reason of this bug and of bug 211275 is probably a glibc issue. According to the glibc guys, the bug will be fixed on 2.11.1, which should be out before the end of this month. I am currently using 2.11, but I will bump it up as soon as possible and report back if I still have problems. Created attachment 57896 [details]

Version: 2.2.1 (using KDE 4.3.3) Compiler: GCC 4.4.2 OS: Linux Installed from: Exherbo Packages After upgrading Amarok to version 2.2.0, it crashes every time I try to start it. I tried several times with a couple of different versions of Amarok (2.2.0 and 2.2.1) and Qt (a few versions around 4.5, as well as 4.6 from the repository). Qt versions 4.5 always chashed with signal 11, SIGSEGV. Qt version 4.6 (latest directly from repository as of today) always crashes with signal 6, SIGABRT. Following, are the backtraces of two of the runs I tried. On both cases, the signals are sent after a QString::append(), according to the backtraces.
