It seems that requesting the blob after it has been inserted into the blob store but before it's been materialised onto the file system causes this error.

Ah ja, that was indented as an integrity error (I've wiped my blobs folder or misconfigured my node) but I can see now that there's a valid case for requesting the file too early .. we could still leave it? Or does it look too scary?

[sandreae]

Yeh, it's good info to have if you're debugging, but a bit scary if everything is actually fine. Maybe just pushing it down to debug is good.

Cool, we're warning already for the misconfiguration case.
