You are on Windows? Perhaps this is an issue with the windows file handling.

Can you comment on this bug, and also save those .couch files in case we need to analyze them?

Corruption like this should be impossible, but this is the second case we've heard lately,
so I'm guessing it is a Windows issue.

Please comment on this bug with information about your machine enviroment (OS, Filesystem,
Disk size, etc)
