[Yt-dev] possible bug?

[Britton Smith]

I'm a bit more confused that it's also happening in serial, but that will
make debugging easier.  Let us know when you track down the last working
version.  In fact, if you just want to insert a couple print statements into
the write_filtered_list routine in HaloProfiler.py, you might be able to
figure out just where it's hanging up.
