[Qt-interest] Qt 4.6.2 / Mac OS X: Phonon crashes on exit

[R. Reucher]

Hi all,

I searched the archives and google'd around a lot but couldn't find any 
matches to my problem... I'm seeing crashes (segmentation faults) for all Qt 
Phonon applications on exit. Although I wasn't convinced, I first thought it 
may a bug of my application, but then I tried the qmusicplayer example which 
also crashes (at the same place):

Do others see this as well or is it just a local issue?

I use this framework:

Thanks for any advice!

Regards, René
