[Trac] PyObject_Call error using mod_python with Apache 2.0.54.

[Bill Williams]

I am trying to get trac up and running using Apache 2.0.54.

Here's my environment:

Linux 2.6.8.
Python 2.3
clearsilver 0.10.13
mod python 3.2.8
pysqlite 2.2.2
sqlite 3.2.5
trac 0.9.5

I can run tracd and everything seems to work.

I did perform the test located in the mod_python directory after I 
installed it and it did not report any errors.
I performed the test for pysqlite after it was installed and it did not 
report any errors.

Here is the error_log I get from apache when I try to access the project:
