PyFinalize crash when mixing sip and PyQt-Builder extensions?

I am getting a crash on exit when I include both my basic sip extension and
PyQt-Builder extension. If I A) only import my pure sip extension in python
and not the PyQt-Builder extension, or B) change the sip extension builder
to PyQt-Builder, it doesn't crash. Import order doesn't matter.

It's complaining about a pointer being freed that wasn't allocated.
I'm not sure where to start with that stack trace. I'd just change the
project builder on the pre sip extension but it's shared with a server
process and I need to avoid a Qt/qmake dependency.
