I can't add new milestone.

[tdkim@…]

I tested Trac -r 2387.

When i add new milestone.

Trac detected an internal error:
'NoneType' object has no attribute 'replace'

Traceback (most recent call last):
  File "/usr/lib/python2.3/site-packages/trac/web/modpython_frontend.py", line 206, in handler

Fixed in [2388].
