Happens here as well, the problem seems to be with the OpenSuSE build. I was encoding to FLAC though
Reported to OpenSuSE Bugzilla: https://bugzilla.novell.com/show_bug.cgi?id=535456
Why did you close this as invalid? The one I reported that's one of the duplicates is with Fedora. It's not just OpenSuSE. Bugzilla needs to have some way to get more information from the duplicate reports without having to click through each one. :/
yeah, the justification for such is missing, reopening. (feel free to revert when/if such information is provided).

I agree with FiNeX, it's the same bug as for FLAC (bug 198467). AFAICT, the fix is simple, there's an unsafe delete d->process; in K3bExternalEncoder::initExternalEncoder which can interfere with slot processing, changing that to if (d->process) d->process->deleteLater(); should fix this crash.
Created attachment 37189 [details] Proposed patch Can anybody please test the attached patch?
