I have a MultiSearcher being created off of several indices on my
computer. It generally works, but sometimes I get an abort, with the
following backtrace (in the thread that I assume caused the abort)

The code isn't interesting; it opens a few IndexSearchers and attempts
to put them into a MultiSearcher. The crash happens during the
creation of a specific IndexSearcher, every time. If I open python
command line and open the index myself, it works fine. The only
difference that I can think of is that my program is running
multi-threaded with SOAPpy, but I am overriding threading.Thread with
PyLucene.PythonThread. Any suggestions in tracking this one down
would be appreciated.
