Server error on export XLS

I'm a complete newb to school tool and Zope
I had the same error on a new install with SchoolTool 2009.04dev on My Linux Mint (Ubuntu) System.
Just created some test courses and 2 sections.

Also previously I tried the import of the test data and I got similar "Index out of range" error
