maximum recursion depth exceeded in cmp

[anonymous]

Hi,

I am running trac 0.9.6 on Fedora Core 4 (AMD64), with Subversion 1.2.3 and Python 2.4.1. I get a "maximum recursion depth exceeded in cmp" error when I am trying to view one of my changesets. I can view the changeset before and after this one with no issues.

Any help would be greatly appreciated,

thanks,

Ken
