Did you try removing then re-adding the server account in iCal? That is 
certainly the first thing to do if things start to get out of sync. 
Modifying data on the server should be a last resort. If after re-adding 
the account in iCal, it still has problems, if you can, tar up the user's 
calendar data and submit that in a bug report so we can try to reproduce 
the issue here.

If an account reset shows the old data, then iCal never sent the changes to 
the server. Or if it did, the data was somehow reverted. Are you doing any 
kind of backup/restore of the data on the server itself?

Is this a one off or have you seen lots of these?

The error log is actually a little more verbose that it needs to be right 
now and is logging things that are not strictly errors. What you showed is 
"normal" for the server.
