Bug 357462

I was trying to decrypt a message which had no GPG version header in it. I would get a "Decryption failed" notice. When clicking on the "Details" button, it would show the program's steps of decrypting, but would also display the message in there. So I figured it was weird that it says failure, but has the message decrypted correctly anyway. I have since did more testing with this bug, and found an easy workaround. All that was missing was a blank line before the cipher-text. Problem was the sender of said message uses a different GPG frontend that when using the --no-version option, doesn't include that blank line.

Reproducible: Always

Steps to Reproduce:
1. Be sent an encrypted message without the version header (and no blank line/whitespace between the begin PGP message header and ciphertext.)
2. Decrypt message
3. Check for more details, find message in there.

Actual Results:  
I was able to read my message within the detailed program logs of the decryption failure notice.

Expected Results:  
Ideally, it should have been able to detect whether or not there's a whitespace/version header or otherwise isolate on the cipher-text, and decrypt text accordingly without causing a false failure. 

Of course the simple fix is to add in a whitespace yourself between begin pgp message header and cipher-text.
