Python segfaults after pyrasite tries to connect

[robintw]

I'm using the standard OS X Python version, and when I run pyrasite --verbose 7407 helloworld.py it appears to hang, until I press any key in the window which is running the Python process - at which point the Python process segfaults and I get the following errors from pyrasite:

0x00007fff8c8c83fa in select$DARWIN_EXTSN () from /usr/lib/system/libsystem_kernel.dylib
[Inferior 1 (process 7407) exited normally]

The program being debugged exited while in a function called from GDB.
Evaluation of the expression containing the function
(PyGILState_Ensure) will be abandoned.
You can't do that without a process to debug.
History has not yet reached $1.

Any idea what I'm doing wrong?

I also had a segfault when trying to pyrasite-shell:
