Error while updating existing milestones

[vdierks@…]

I tried to set a milestone as default:

Traceback (most recent call last):
  File "/usr/lib/python2.4/site-packages/trac/web/main.py", line 387, in dispatch_request
    dispatcher.dispatch(req)

You probably have an installation issue:

trac.ini file should be writable for the web server (same file permissions as db/trac.db).
