Crash while recording video with audio

This crash started to appear in our logs. I couldn't find any pattern and I couldn't produce the error with the devices I have.

CGE::CGEVideoEncoderMP4::getAudioStreamTime()
Maybe the function is called with a dangling pointer? Please check if this is called after the object released.

It has been more than a year, but you were right. Another exception was causing the screen to close without the object being released. After I fixed that, it has never occurred again.
