How to Reproduce

While doing a GET operation on /changeset/196, Trac issued an internal error.

The link is obtained from the Timeline. When I try to see the changeset, I get an error page instead.

Request parameters:

{'new': u'196'}

Seems to be a duplicate of #7310. Which SCM backend are you using?

I tried the solution for perforce in #7310, however the error did not change

Make sure you modified the file that gets really used by the server and/or restart the server.

Anyway, this is a PluginIssue, see ​TH:PerforcePlugin and in particular ​#TH2338.
