Amarok and Systemanager Crash

[Mario Young]

Hello,

I recently update to Qt 4-5rc1, but now I'm having a crash running
amarok and systemanager

In amarok the crash happened when I open amarok
and in systemsettings happened in General -> Multimedia

In the file:
KDE/kdebase/runtime/phonon/libkaudiodevicelist/hardwaredatabase.cpp line 129

128 - const bool opened = cacheFile.open(); // QIODevice::WriteOnly
129 - Q_ASSERT(opened); <-- HERE
130 - QDataStream cacheStream(&cacheFile);

Function:
HardwareDatabasePrivate::createCache


systemsettings log...
