>   What version/revision of Pigeonhole you installed.

I'm using recompiled debian packages from http://xi.rename-it.nl/debian/ which already come with pigeonhole. The last changelog entry is from 2010-08-14.

I'll work on these. The server is hosting a few thousand accounts, so it's hard to identify specific scripts.
