--- Comment #2 from Juan Luis ntrrgc@gmail.com 2012-07-10 20:49:47 CDT --- It does have a home page, but it's quite broken right now. No downloadable test, AFAIK.
On the other hand, reading the index entries, I have noticed that all of them are plain ascii, with no more than [A-Za-z_.].
I wrote a little experiment (http://pastebin.com/DYkyPvAR) and run it both in wine and windows. This is the result: http://mergely.com/eHJ1cHwW/
There can be noticed that order of '_' and '.' (characters which are used in the index) are reversed in order, among others. That might be the cause of the crash.
