KDE 4 "crash"


About one out of every 4 or 5 times i start KDE i get a KDE Bug Reporter window saying KDE crashed, but everything is still running fine. It doesn't affect performance, it's just something I'd like to fix because I'm a little anal. Here is what the developer info says on KDE crash reporter window:
Code:
Application: KDE Daemon (kdeinit4), signal: Aborted

Seems something regarding KDE sound system (there are traces coming from libasound and kded_kmixd from the stacktrace you reported) is going awry.
Try looking at sound settings in KDE control center.

Ok thanks for such a quick reply, what should i look for? I just did a general look into the Multimedia tab, my default device is set and work for audio output, recording, and webcam (even know that doesnt have anything to do with audio)

Try disabling kmixd service under "Boot and shutdown->service management" (I'm translating on the fly from my italian localization, so the names could be kinda different).
