This is the real error, the following is just a warning caused by it:

I've added some extra debugging in Subversion that should tell us which 
file failed and how. Please could you try building the latest code and 
see what it reports when this happens?

I think S3 has some issues with newly uploaded files taking some time to 
appear on the store, particularly if the S3 server that you're using is 
not your home server, so that may be related (unless s3fs has a way to 
hide that from the user).

Cheers, Chris.
