Nick,

I haven't seen this problem myself.

Which version of SE are you using on the 2.6 hosts?  Can you try the
other example SE scripts and see if they generate the same types of
data?

Orcallator.se uses the SE supplied classes to get this information, so I'm
guessing right now its an issue with SE.

Best,
Blair
