@justus can you provide an example of the gpgme code you're using that generates this weirdness?

werner claimed this task.
werner added a subscriber: werner.

That seems to be gpg 1.4 which we do not fully support.

dkg reopened this task as Open.Thu, Oct 24, 9:22 PM

@werner, are you saying that gpgme is not fully supported for use with gpg 1.4?

If that's the case, this bug report should be resolved by changing gpgme to detect that it is being used in an unsupported configuration and having it emit a warning at least (perhaps it could also refuse to initialize a context if it is asked to use an unsupported version).

werner closed this task as Wontfix.Fri, Nov 15, 9:18 AM

it is just that we won't fix that for gpg 1.4.
