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

[R. Reucher]

Hi,

as a follow up to my problem with Phonon 'post mortem' crashes on Mac OS X 
I've now upgraded my installation to Mac OS X 10.6.3 (I had 10.6.2 before - 
sorry, should have mentioned this earlier). Anyway, the problem remains 
nearly the same:
