I've attached the test script I'm using (fork.py):
- The script works without the "import gtk" line
- Including the "import gtk" line I get the following error:
Gdk-Message: locale not supported by C library
parentpid: 4348
childpid: 4349
Gdk-Message:
** ERROR **: sigpipe caught
- Running it through gdb:
(gdb) run fork.py

Hope this helps somehow ...
