The application works fine, but closing the main window results in a

backtrace) the crash is not in my own code, but somewhere inside the
gtk(mm) library.
Could you provide the backtrace? that might be helpful information.
Sometimes I don't get the segmentation fault, but only a large number of
errors. See attachment for both the backtrace and the errors.
Also, trying to pare down your example to a more minimal test case
might help to pinpoint the problem.
I'll try to reduce the example even more.
