New crash information added by DrKonqi
kmix (3.8) on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2
- What I was doing when the application crashed:
I plugged in an M-Audio Xsession pro and the Kmix window was open, it crashed instantly.
-- Backtrace (Reduced):

If you unplugged the card before, this crash can be explained. There is a unplug/replug problem since distributions changed from HAL to UDEV. It is fixed in KDE4.7.1 and trunk: http://mail.kde.org/pipermail/kde-hardware-devel/2011-August/001455.html Can you retry with KDE4.7.1 or KDE4.8? I didn't updated to 4.7.1 yet, but I'll test it as soon as it's updated. I think this cause is possible as the bug appears when I remove/add ALSA module of V4L2 tuner. I think for UDEV it's as if the card was removed and inserted back. No reply from bug reporter. Closing bug. Sorry for no reply. Can't reproduce for 4.8.2 anymore so it seems to be fixed. Thanks for closing. |
