I don't think that this is how it is meant to work. It's possible you've a
coding error, perhaps something like a value of $cat_atts["value"] that is
'*' or something, but more likely a bug.
I'd suggest downloading version 1.N.4 and switching on the debug flags in
the evaluate functions to get a "stack trace". This might help isolate the
problem and determine if it is a bug or a coding error. If you are still
stuck perhaps sending us a portion of the xml and the complete php file
might allow us to reproduce the error ourselves?
The evaluate() function has several known problems, and sadly it wouldn't be
all that surprising if there were some more. Version 1.N.5 is going to have
a complete re-write of the evaluate() function that should give us MUCH
better performance.
