Application: amarok (2.3-GIT)
KDE Platform Version: 4.4.3 (KDE 4.4.3)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
When playing one or several tracks, suddenly Amarok crashes. The backtrace is not ideal, it seems to indicate a taglib problem though.
Using Amarok 2.3.1-git of today, KDE SC 4.4.3 on Kubuntu 10.04, taglib 1.6.3

I never experienced this with the upcoming Amarok 2.3.1, in use since several weeks, so it might well be an Amarok, not a taglib problem.

 -- Backtrace:
Application: Amarok (amarok), signal: Aborted
