Enabling DynVariable module breaks work queue module functionality

[Danny Sauer]

When I enable the current Subversion release (9965) of the dynamic variables plugin, I get a couple of errors logged and the work queue module doesn't load - regardless of whether or not I have any dynamic variables configured in the query.

This is trac 0.12 on an RHEL5 system using Python 2.4

Here's the two messages which get generated per request:

Maybe or maybe not related, if I actually use a variable in the query, the dropdown also doesn't become a dropdown - I just get a text field where I can enter the name of the field.

(In [9969]) refs #8614: may fix "KeyError: 'dynvars/htdocs'" under python 2.4 but not sure.

[Rob Guttman]

I'm not sure if my fix will work or not under python 2.4. Can you give it a try and let me know? Thanks.

It works correctly on my 2.4 system now. Awesome - this is way better than making a bunch of links to the current page with the parameter pre-populated in the URL. :)

Great! Closing ticket.
