Hi,
sorry but i think there's no wizards here ;)
maybe post some code, or describe what are you doing in your program.

the only way i can help without any knowledge about your application is quoting qt manual:


QMutex::~QMutex ()
Destroys the mutex.
Warning: Destroying a locked mutex may result in undefined behavior.

consider using QMutexLocker:

The QMutexLocker class is a convenience class that simplifies locking and unlocking mutexes.
