I'v debugged that a bit, and I can confirm the bug. It is caused by the
wrong use of the binary 'is' operator to compare strings in the 'web.py'
module, which accidentally worked on python prior to version 2.4.
The control flow falls through the comparison around line 2057 where
it is assumed that the 'type' variable is either 'test' or 'resource'.
As both tests fail, the 'item' variable remains unbound, and thus the
exception is thrown.
Solution: replace the use of 'is' by '==' to compare strings.
