I'm trying to debug a segfault i get in a multithreaded, qt webkit application. I installed python-dbg for the purpose of giving me pretty printing in gdb and get the following error on start
python2.7-dbg node.py

Original exception was:

I get the same thing when I run a version of the script that doesn't use msgpack...

in both cases its looking Py_InitModule4... any ideas python experts? Code runs fine (except for the segfault much later) with normal python 2.7
If there's an easier way to get pretty printing in gdb I'm open to that as well. Basically just looking for a python style stacktrace
