Running version 1.4.8 and Trac 0.12. Catalogs and Test Cases can be created fine with no errors. However whenever a Test Plan is created, the Plan creation works, but after that, anytime I try to view the Catalog that its associated with, I get the following error:
ParseError: malformed start tag: line 1, column 801
I'm currently working around this by commenting out line 247 in wiki.py
self._get_testplan_list_markup(formatter, cat_name, mode, fulldetails)
as the problem appears to be with this function but then I can see the Catalog but not any of its Test Plans.
