python error when going to the roadmap page

[anonymous]

I went to ​http://siprouter.onsip.org/trac/roadmap

and I got :

Oops...
Trac detected an internal error:
empty string for float()

with the Python traceback :

Traceback (most recent call last):
  File "/usr/lib/python2.3/site-packages/trac/web/cgi_frontend.py", line 130, in run

  File "/usr/lib/python2.3/site-packages/trac/ticket/roadmap.py", line 108, in calc_ticket_stats
    spent_work += parse_time(ticket['tt_spent'])

that's not our code … so we can't fix it.

To clarify cboos' comment, it appears that the administrator of that site has made modifications to the Trac source code and the error is in those modifications. As such we can't help you, so you will need to contact the site's administrator to get them to correct their errors.
