SIGSEGV in libpango-1.0.so

[Stimpy84]

I receive the following fatal error when disposing a GC object. I'm not certain exactly where the error stems from as the construction is fairly complex and concurrent.

If anybody needs some information about a specific implementation, I'd be happy to take a closer look, but I'd need to know more or less what to look for.

I forgot to attach the log file. It appears that it has nothing to do with GC objects, but originates from disposing the Display object. I'm having difficulties finding the source of the problem
