More information. I was able to compile a program in C++ that does basically 
what the above does, but there is no segfault. This leads me to believe there 
is a problem with PyQt.

I think I've tracked it down to QSqlDatabase.removeDatabase(), but I am not 
certain as it will seg fault in other places. I'm working on getting the 
-debuginfo modules installed so that I can view the core dump through gdb.
