GPGServices not answering and then becoming unresponsive after trying to decrypt a certain message

Reported by steve | August 26th, 2017 @ 02:35 PM | in 1.11.2 (closed)

A user reported a "Can't decrypt error = 0" issue using GPGServices.
macOS 10.12.6
GPG Suite 1952n

When trying to reproduce the problem, I observed some interesting behavior.

  1. Open this discussion user-comment
  2. mark the message in question and decrypt using GPGServices

Currently

GPGServices hangs and becomes unresponsive. Also unresponsive to any further operations. An error is shown after a while "The OpenPGP: Decryption Section service could not be used because the GPGServices application did not respond to a request for services.
Try reopening GPGServices or contact the vendor for an updated version. (see attached screenshot)

Expected

GPGServices should not hang. Instead show a comprehensible error message about a damaged OpenPGP message.

The offending message with long dashes instead of normal dashes at the beginning and end is this:


-----BEGIN PGP MESSAGE---— Version: GnuPG v2
