Crash when using qaac encoder

[Nero]

Yeah, that's right. It crashes and the job queue stops, saying that the aac file wasn't created.

I tried to get more information by changing the debug to level 9.
So I found this error message:

Qaac output: ERROR: CoreAudioToolbox.dll: The specified module could not be found.
process finished with exitcode: 2 and exitStatus: 0

Any idea what that might be?

I think it's no problem with dependencies, because when hybrid checks for them, the debug log says:
