I get the following error in trac.log

raise TracError, 'No handler matched request to %s' % req.path_info
TracError: No handler matched request to /site/graphviz/32a4c35133da4624102816e63000d21de146fadd.dot.gif

everything else looks alright. running version 0.9.4.2 on debian linux

Can you provide a bit more about your environment?

Which web server? Apache? Tracd?

Can you post your trac.ini file?

I'm unable to reproduce the problem. Without additional details, I'm going to close this as works for me.

The graphiz !plugin makes an image, it just isn't picked up by trac for some reason. Pathname perhaps?

When more info is needed, just send me an e-mail.

After a little research I found that the cache directory can't be freely chosen. changing it in /opt/trac/htdocs/graphviz/ solved the problem. Perhaps this needs to be changed in the code someday, the hint graphviz/md5sum.gif isn't exactly correct.

but it works!
