      Description

      Several times per week I receive a sudden crash. Mac OS X crash reporting information is attached.

      At the time of the crash, I am not doing anything special, I usually don't even have the window on the foreground.

      I am using a dual screen setup and Qt Creator is running on my main screen.

      For easy reference, this is the backtrace of the crashing thread (full information in attached file):
