I commit the changes by pressing the 'Save' button in the Save/Discard tab.

The actions are (and there are no other users working on this Zope
installation):
- I do a fsrecover.py on my Data.fs to test whether there are
   errors. Result: no errors
- I start working in my version.
- I edit a DTML Document and add the string 'Test' somewhere.
- I commit the changes by pressing the 'Save' button.
- I quit working in my version.
- I do a fsrecover.py on my Data.fs again: Result:
ZODB.POSException.VersionLockError: ("'\\x00\\x00\\x00\\x00\\x00\\x000\\xa4'", 
'/Test/Test Version')

At this point I do not get an error using the ZMI or using my application.
But I think that these errors accumulate over time and eventually my
Data.fs is really corrupt (as it has happened two times so far).
