[Qt-interest] Qt Phonon Media Source crashes

Hi all,
I'm developing an Qt Phonon application.
it was working fine w/ Qt 4.7
then I decided to migrate to Qt 4.8

And now I got a crash in this line:

_mediaObject = new Phonon::MediaObject(_centralWidget);


_mediaObject is a Phonon::MediaObject

and _centralWidget is a QWidget*


at first I saw that my system had 2 Qt installations (one dylib and
other as framework)... and it was confusing somehow...

and even my Qmake pointing to the framework I still get my application
linking to dylib...

So I deleted manually the dylib (I know maybe it was wrong but I
didn't figure out a better way to uninstall that =x), and now my
application successfull link to framework, but crashes at that line


the otool -L output

	phonon.framework/Versions/4/phonon (compatibility version 4.4.0,
current version 4.4.0)

The Phonon is 4.4, maybe it's a problem?

and here is the crashreport:
