django/selenium testing: how to debug a segmentation fault? -

when running django tests using staticliveservertestcase , selenium, encounter occasional segmentation faults.

these crashes seem random: run same test 10 or 20 times without changes , segmentation fault happen 1 or 2 times , @ seemingly random points in test. information crash nothing: segmentation fault (core dumped) python manage.py test.

i wondering there anyway find out why happening? in other words, how debug crashes during python tests?

i tried python -m pdb manage.py test, not allow tests run (it stops @ first import statement).

i have tried

updating python packages. using python 2 in virtualenv , have packages date.

updating os. using arch linux , date.

tried on different computers. same thing. though using arch linux on computers.
