No, sorry. But this doesn't surprise me much you don't encounter a segfault: Everything happens during the destruction of a dropdown widget, so the system is in a sane state before the destruction starts, and it may still be after the destruction ends. So you have to be quite unlucky to get corrupted memory during this short lapse of time. > And please add a gdb tracelog :) Better than a gdb trace, here comes a valgrind trace.
