Crash when viewing active tickets

[mick@…]

Each time when I click on roadmap -> active tickets of any milestone, the script crashes, see traceback below:

Traceback (most recent call last):

    dispatcher.dispatch(req)

There is no such code in Trac:

  File "/data/devjavu/current/trac/lib/trac/web/chrome.py", line 79, in armor_email
    if str(email).find('@') != -1:

The original file has been patched, see tags/trac-0.10.4/trac/web/chrome.py#L79​
