error on a “Predicted hours to work: xxx.xx” link

[mhenke]

I am receiving an error when clicking on the a “Predicted hours to work: xxx.xx” link. It goes to something like this http://xxxxx/ticket/423/ebs and I get this error screen.

---

Trac detected an internal error:

KeyError: 'ticket'

This is probably a local installation issue.
Found a bug in Trac?

If you think this should work and you can reproduce the problem, you should consider creating a bug report.

Note that the tracmastertickets plugin seems to be involved. Please report this issue to the plugin maintainer.

Before you do that, though, please first try searching for similar issues, as it is quite likely that this problem has been reported before. For questions about installation and configuration of Trac or its plugins, please try the mailing list instead of creating a ticket.

Otherwise, please ==== How to Reproduce ==== While doing a GET operation on /ticket/423/ebs, Trac issued an internal error.
