It turned out to be a bug in my code after all, which I couldn't find at first with valgrind (it generates so many false alarms I can never find the real bugs among them), but it turned up with MALLOC_CHECK_ and some experimentation.
Sorry for the bogus report. I can't seem to find a way to close it. -- Crash after GtkNotebookWindowCreationFunc https://launchpad.net/bugs/73270 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
