[Daniel Schürmann (daschuer)]

Not sure if this is the cause for the crash but soundsourcemediafoundation.dll has unmet dependencies:

http://en.wikipedia.org/wiki/Media_Foundation
"Media Foundation will not be available for previous Windows versions, including Windows XP."

[Daniel Schürmann (daschuer)]

OK, wrong way, soundsourcemediafoundation.dll is not the cause of the crash.
If I delete the soundsourcemediafoundation.dll the error message disappears, but the crash still exists.

I should have noticed:
I run WinXP in a VirtualBox

Here is the back trace without symbols (sorry)

Tested with Mixxx 1.11.0-beta1 bzr r3279.

It is possible to start Mixxx when I change
[Waveform] WaveformType from 6 to 2 (Software filtered) or 0 (empty)

Wen I try to switch back to one of the GL wafoform types in preferences Mixxx crashes again.

Win XP is able to run the QT openGL examples like "2dpainting" and "grabber", so it is in general possible to run openGL Widgets in Virtual Box.
