How to Reproduce

While doing a POST operation on /admin/ticket/policy, Trac issued an internal error.

Steps to reproduce:

1. Go to Submit Policy in Admin area (Web frontend)
2. Enter name in unlabelled text box and click "Add Policy" button
3. Click either of the "+" buttons on the next screen and the error is thrown.

Obviously, this makes the admin interface completely useless.

Request parameters:

{'panel_id': u'policy', 'cat_id': u'ticket', 'add_condition_policy1': u'+', '__FORM_TOKEN': u'10d9980f6a6c7dbaf9804f3d', 'path_info': None, 'policy': u'policy1', 'new-policy': u'', 'add_action_policy1': u''}

python 2.3 strings don't have rsplit. please upgrade your python to 2.4 I've noted this on the TicketSubmitPolicyPlugin wiki page under ​Getting TicketSubmitPolicyPlugin

[Jeff Hammel]

support rsplit for python 2.3

You can try this patch wherein I've reimplemented the rsplit functionality for python 2.3. It doesn't really make sense to put this into the TicketSubmitPolicyPlugin code base as:

1. its special cased to the two instances of rsplit in ticketsubmitpolicy.py
2. it is code bloat for the normal (python >= 2.4) case

I don't plan on maintaining this patch in the future, so please upgrade, but in the mean time this should work (I hope)
