Generic suggestion #1: When your program is seg faulting, run it under
a debugger to see where it's segfaulting and get a stack trace if you

It's slightly more complicated than usual in our situation, because
we're dynamically loaded into python.  The good news is that gdb handles
this well.  If you're not familiar with gdb, now's a good time to
learn how to use it.

See http://www.gnu.org/software/gnuradio/doc/howto-write-a-block.html#debugging

Generic suggestion #2: When a program has a problem, find the smallest
test case that reproduces the problem.
