Description Mark Rooks 2012-04-05 08:07:17 UTC
Application: kmix (4)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.3.0-8.fc16.i686.PAE i686
Distribution: "Fedora release 16 (Verne)"

-- Information about the crash:
- What I was doing when the application crashed: had entered username and password and selected KDE Plasma Workspace as the desktop manager.

- Custom settings of the application: Doesn't happen in GNOME 3
Could this be linked to 2x sound out devices (RV635 ATI video card/w HDMI out and regular sound card)
I have noticed there is a new virtual device in pulseaudio trying to link the DLNA server and pulseaudio

The crash can be reproduced every time.

-- Backtrace:
Application: KMix (kmix), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".

New crash information added by DrKonqi

kmix (4) on KDE Platform 4.8.2 (4.8.2) using Qt 4.8.1

- What I was doing when the application crashed:

Logging into KDE, the application crashes after initially starting.  Restarting the application does not cause it to crash, but logging into KDE pretty consistently crashes it.  One other thing I noticed: If the volume adjuster bars are vertical instead of horizontal it rarely crashes (if ever).
