strange problem with pydo

Hello,

I've have been using PyDO with no problems until yesterday. I'm sorry to admit but
I made some changes (and I don't remember all of them) and PyDO stopped working.

As of now, PyDO works fine via my shell scripts and via the command line python interpreter.
But when using it via the web (apache/mod_python), apache returns a zero-length reply. (browser says
"document contains no data"). I've confirmed that mod_python works okay, but any page that 
accesses PyDO causes the zero-length reply. There are also no error messages in the logfiles.

My environment:
Apache 1.3.27
mod_python 2.7.8
python 2.3
PyDO (latest from CVS)
mysql-python (currently 0.9.1 but the same problem happens with 0.9.2 and 0.9.3b2)

I can even run a raw sql statement by accessing a pydo class's connection object.
But then doing a PyDOclass.getUnique(..) causes the error again.

Any ideas what could be causing this?

thanks

Kevin
