[sword-devel] CLucene crash

[Karl Kleinpaste]

A Xiphos bug report...
   https://sourceforge.net/tracker/?func=detail&aid=3291274&group_id=5528&atid=105528
...observes that searching for "[est]" in FreJND, without specifying
regular expression, causes Xiphos to crash.

He's right:

Using the shorter string "[est" does not crash.

I have no idea what we could suggest.  If there is a workaround, I'm all
ears, but for now the report is simply closed.
