 First of all you should really use wx 2.8.7, it's 100% compatible with
2.8.3 so you shouldn't have any trouble upgrading to it but it contains
many bug fixes and while I don't remember anything related to this one, you
should still try it first.

 So in the minimal sample too?

 Just to confirm it, did you run it with --sync command line option?

 Can you check if GetPixbuf() returns something valid (at least non NULL)?

 It's really difficult to do anything about such bug without being able to
reproduce it or even see the details of the stack trace... Does the bug
appear only when using some visuals by chance? Which one do you use in
fact?
