 When importing _xapian, the Python bindings segfault. Here's the output
 from valgrind. It's a little more useful than gdb's backtrace, but I'm
 still unsure why its happening there. All other tests in core indicate
 that this should work.

 In this process I also worked on bumping the swig bindings to 2.0.2.
 Python needed the attached patch to get it building.
