I've uploaded an image with debugging information (about 10MB) to the
same address:

  <http://weitz.de/files/regex-coach.bz2>

You /might/ get a more informative error message with that one.

As to why the application doesn't quit when it should - that's another
question.  Again, I haven't seen that before.  Ubuntu seems to be a
bit strange.  I'm using Debian and I thought they were pretty similar
but obviously they aren't.

Thanks for testing,
Edi.
