Since upgrading my four installations of coWiki to 0.3.4 (from a March 11 
0.4.0-cvs), I've been experiencing what I think is being refered to as 
this "bad magic" stuff.  I edit some pages, and a few days later they will 
have reverted to a much earlier version.  I can usually revert them back 
to the most current version via the history, but it is a very troubling 
problem.

I do not allow guest write access to any of my pages.  Is there perhaps a 
bug/security exploit of sorts that would allow a malicious guest to 
trigger this?
