That means that the object lives inside is NULL or has been deleted. eg. It's perfectly fine to say: Monster* shrek = NULL; shrek->tellJoke(); ... and tellJoke() will run, but as soon as it tries to access a member variable (a variable that lives inside the "shrek" object), then it will crash. This is what you're seeing when the mutex lock is crashing. So... your MidiMapping object is NULL or hasn't been allocated yet probably.
