Comment 1 Mikko C. 2010-10-15 11:51:40 UTC

I can confirm these very strange crashes which seem to be related to either VLC or taglib, most likely not amarok's fault.
Unfortunately, all the backtraces miss debug symbols, which is very strange since I compiled taglib with debug enabled.

For example:
