I'm afraid that the user, expecting something (from bad error reporting in other places) like "Resource 0x23498382 failed to close", will interpret the error message as a further malfunction. However, it does remind me of something pgp did, where a bit string (a key hash, I think) was converted into a sequence of words pulled out of a phonetically-distinct dictionary.
