Redmine

I'm moving redmine (1.0.1) to a new server (ruby 1.8.7), when I installed sqlite3-ruby 1.3.3 on the new machine, redmine dosn't work correctly:

ArgumentError (comparison of Time with String failed):

the problem occurs because with sqlite3-ruby 1.3.3, "settings_updated_on = Setting.maximum(:updated_on)" is a String.

I installed sqlite3-ruby 1.2.4 and it worked fine again.

If this is a issue with sqlite3-ruby rather than redmine, I'd not be surprised, but I would imagine other users might face the same issue, and in that case might be worth noting somewhere.
