Unicode error in Workflow Sandbox

[jdunham@…]

I just installed the workflow sandbox version (​http://svn.edgewall.com/repos/trac/sandbox/workflow, rev = 3025, last changed rev. = 2983) , and I get the following error when clicking on most of my defined reports. The box is running Linux Fedora Core4

Some of the custom and built-in wiki pages have a similar problem, including …/cgi-bin/trac.cgi/wiki/TracIni

I tried checking out 2983 explicitly and rebuilding and installing trac.cgi, but I get the same results

As the workflow sandbox hasn't been migrated to unicode yet, I suspect you are using trunk. Line 36 of util/html.py does not contain unicode.__new__(self, text) in workflow.

Perhaps you need to remove /usr/lib/python2.4/site-packages/trac completely and reinstall.
