-----------------------------------------
Yes, that too.
This isn't THAT important. I suspect it is related to the reason that we
started with quicksort. I added this file to my test set to check for problems
with BiDi texts (here: mixed arab and latin glyphs).
re the exception - are you using the current version, without any changes? It
works for me in 2.0 and 1.8.11.
