Hi, I've seen something like this before when some of the users were remote nd 
were accessing the repository via a SVK mirror. The mirror was reverting 
files prior to committing to what I presume it thought the state should be. 
This was some years ago, but if I recall correctly the commits for the 
reverted files did not have any commit message. I don't know if it was an 
artifact of the setup we had (I never did the setup) but commits coming via 
the SVK mirror would be from a single user but the real user would be part of 
the commit message. Could something like this be happening for you?

Campbell
