 Priority:  low                   |   Milestone:

 Severity:  minor                 |    Keywords:       
----------------------------------+-----------------------------------------
 When I click on the latest changeset, trac will pauses for about 20
 seconds then return with


 {{{
 Oops...
 Trac detected an internal error:

 maximum recursion depth exceeded


 }}}

 This was working before although only with minor changes.  The new
 changeset has quite a bit more changes but nothing that should break it,
 imo.

 Pasted is the python traceback:
