don't allow malformed md5s when creating file handles

Description

A user should not be able to create a file handle object with a malformed MD5 (like the string 'test'). We cannot check if the MD5 is correct, but we can check if it is in the right format (a 128-bit hash represented as a sequence of 32 hexadecimal digits, I think).
