That is a possibility as we really don't use or test the file system 
implementation any more (beyond maintaining it solely for the purpose of 
migrating data to the SQL DB).

Still I am a little surprised this is happening as ETag handling is a 
pretty basic piece of the protocol - but if there is a bug we would likely 
tell you to upgrade since you have a pretty old server version. If you want 
to try and debug this further (rather than doing an upgrade) then please 
try and get HTTP protocol logs of a bunch of requests prior to and after a 
412 response.
