This is a fix for a language feature which worked in python2.x,
broken/unsupported in 3.1 and added back in 3.2.

See: Previously it was illegal to delete a name from the local
namespace if it occurs as a free variable in a nested block
http://docs.python.org/dev/whatsnew/3.2.html#other-language-changes

Since the script was ported straight from python 2.3 -> 3.2 I didn't
notice this.

Its odd that your not getting a proper traceback, if I add in a
SyntaxError it reports the file and line number, could be a problem
with this specific error not giving a traceback in py3.1 since I never
had this problem even before the upgrade.

Commenting release/scripts/op/uvcalc_lightmap.py:278 should fix it.
