Hmm, I get:
...
$ gdb -q
(gdb) maint selftest python
Running selftest python.
Ran 1 unit tests, 0 failed
(gdb)
...

Do you have any idea how I could reproduce the fail you're seeing?

FWIW, I don't understand the '5' showing up.  The test is using
execute_fn_to_ui_file which should take care of redirecting things.

Thanks,
