- Do you think you will be able to reproduce the crash at will ? Thanks
I'm not sure what really causes the crash but it has happened twice. I suppose I could do it again yes...
I've set this report to WAITINGFORINFO, I cannot reproduce the crash :-(
I cannot reproduce this crash either. Unless @Maxime still experiences this behavior, I am going to close this bug soon.
After taking a closer look at the backtrace it seems like this is a crash in libxine, which is no longer in use. Closing.
Wow, I had forgotten all about that. Sorry for not closing it sooner!
Julian, it is thread 1 which crashes. This is most probably unrelated to the xine thread, but would need a valgrind log to investigate the memory corruption. Let's avoid these steps for the Qt4 versions, though.
Apparently I suck at reading backtraces... I guess we can still mark this RESOLVED, or should I reopen the report in such a case?
No, because the is the Qt4 version, which is unmaintained anyway.
