Version is SVN trunk from 28-September-2008
Is this a one-time crash or reproducible? Do you have a self-compiled/installed libxine? If you can reproduce please show me the debug output of % PHONON_XINE_VERBOSITY=3 amarok
No, I could never reproduce the crash. It seems to have been a one-off thing. So feel free to disregard it, if you can't spot an obvious bug.
Alright, if somebody ever hits this one again, reopen. But generally - from the code - this failed assertion should be impossible, but perhaps there's a race condition I've overlooked.
Bug 197312 seems to be the same but on KDE4.2.90 / Phonon4.3.1. @Matthias: could you take a look on it ? Thanks
