Syntactically invalid blobs become inaccessible #106
Description
It is possible to submit a PUT request containing an invalid object. If this is done, the blob seemingly becomes inaccessible; GET requests appear to return normally but with undefined or unusable contents, and attempting to view the blob's webpage returns a 524 timeout. Another PUT request can still edit it, but this makes debugging more difficult, as one cannot see the data which caused the error nor manually correct it. An example can be seen here, which contains an unterminated string.
