Corrupted changetime field prevents viewing of tickets

[mellis@…]

Somehow the changetime field in a ticket of ours got changed to a non-integer number (1129000177.4728). This meant that any report including the ticket in question failed. I was able to go into the database and edit the offending record manually and restore service that way without having to use our daily backup.

We have 30+ users on 3 individual tracs for about 5 months now, this is the first time we've seen this particular error. We upgraded less than a week ago to 0.9b2-intertrac (I think it's [2320]) on a completely new server.

Here is the traceback:

OK, so I think we know what caused this. I deleted a milestone from within the View Milestones page which changed the milestone for this particular ticket to None. The exact change is recorded as:

10/10/05 20:09:37: Modified by mellis

milestone deleted.
Milestone Test Milestone deleted

This ticket had a non-integer changetime and the last change made to it was by the delete milestone function.
