Exception when browsing non-existent revisions

[daniel+trac@…]

When manually requesting a non-existent revision number, the browser raises an exception. The browser should check whether a requested revision number is valid before attempting to fetch / display it, and handle this case gracefully by displaying a more easily understandable message to the end user ("sorry, revision X does not exist in the repository" or some such).

Oops...
Trac detected an internal error:

("Reference to non-existent revision '8' in filesystem '/path/to/svnroot/repos/test/db'", 160006)

If you think this really should work and you can reproduce it. Then you should consider to report this problem to the Trac team.

Go to http://trac.edgewall.com/ and create a new ticket where you describe the problem, how to reproduce it and don't forget to include the python traceback found below.
