Hi, Taco:

Last week you invited me to test the trunk version of luatex. Today I
compiled LuaTeX trunk version
(This is LuaTeX, Version snapshot-0.32.0-2009011719, build unknown)
and used first-setup.sh (change --context tag into experimental as
Mojca suggested) to download the ConTeXt
(MtxRun | current version: 2009.01.17 00:15)
distribution. And after compiling one of my thesis, I found there is a
bug in mathmode. I am not sure whether it is a bug in luatex itself or
a bug in ConTeXt.
