Amarok freezes

Fri Nov 24 00:48:36 UTC 2006

Some of you must have seen my questions on IRC :-) about my strange
amarok freezes.

I'm trying to find where it comes from.

I kind of freeze immediatly after starting playing a track : the mouse
pointer changes to the busy one (I'll call it "partial freeze"). It
completly freezes when the current track is over (I'll call it "full
freeze") I think it could be in ony one thread so I tried killing it
with kill -11 to get a backtrace.

I hope this could help pointing toward a solution ?

Here is the backtrace I get when killing it with segfault during
partial freeze. After it you'll find the one coming from killing it in
full freeze:
