[IronPython] Importing standard Python libs

[Lukas Cenovsky]

I ethinům you will have to dive deeper and debug your code with Windbg. 
It's not so hard - I described the basics (for myself to remember them) 
on http://gui-at.blogspot.com/2010/01/windbg-for-beginners.html.

Basically run you code in Windbg and when you hit exception, you run 
!analyze -v. This tells you more about the exception so you might be 
able to figure out what's going on.
