Here's a way to find out... as long as you're running FileStorage, you can
run this script against your Data.fs via "list_transactions.py
/your/path/Data.fs" (even if the Data.fs is open).  Then you can compare the
output of the script against the stupid log file to see if there were any
writes to the ZODB at the time of the conflict.  Other folks have complained
about this and we're trying to isolate the problem... if you have time, it'd
be great to hear you report back "yes, there was a write, and here was its
method name", or "no, there was no write at that time, somethings messed
up".
