GPGMail: Mail crashes after trying to sign or encrypt a mail

When I sign or encrypt a mail I get asked to insert my key but the key is not accepted. After a couple of unsuccessful retries I try to cancel the signation/encryption and when trying to send the mail than without, mail crashes.

Not asking for my key.
Accepting the correct key.
Not crashing when sending without signature/encryption.

    Hi M,

    we are very sorry to hear you are experiencing problems with the latest version of GPG Suite.
    We believe this problem is triggered if a user has a custom GnuPG version installed along side of our MacGPG.

    Could you please download and install our latest GPG Suite nightly build and see if it solves your problem. That page also has sig and SHA256 to verify the download.

    Disclaimer: This is a development version which has not been thoroughly tested yet - bugs or crashes are to be expected. Thanks for helping us test.

    Hi, I tried a complete new download but the result was the same.
    I went back to the last version.

    That is very curious. Do you have a crashlog by any chance?

    Well, I thought that - when I created the report - it asked me to attach one and I did.
    But I can send another one if you tell me where/how to find.

    Ah sorry, no, that's a debug log, which contains some information in regards to your gnupg and mail setup. The Mail crash log is specifically created by Mail itself.

    You should be able to find it in your user's Library folder under:

    Hi Matthias,

    thank you very much. I believe this might be a incompatibility with Mail-Act-On.
    Would it be possible to uninstall/disable Mail-Act-On temporarily to see if GPGMail works reliably after that?

    If you can qualify that hint a little bit, I would forward this to the MailTags guys.
    BTW … its a really cool tool - do you know it?

    Well, as I told you I installed the former GPGMail version. Maybe I try it …. but must look when …

    Okay, I did it.
    Same result.
    Crashlog attached.
    There is still another Plugin - MailActOn (but I don’t want to remove this too)

    Hi Matthias,

    thanks for the update. We will talk to the folks at Small Cubed and will let you know, once we know more.

    Thanks for testing in the meantime.

    Ah, one question, since I didn't really understand it. Did you try the nightly?

    .. the nightly built?
    Probably not - I took the one promoted on the home page.

    Ah ok, because that one was supposed to fix your original issue.
    From your debug log it's clear that you have an old custom version of GnuPG installed, which the 2017.2 release has a problem with. The nightly build fixes that problem, and includes all the GPGMail changes for 2017.2

    The nightly link is buried somewhat down this discussion in comment 1.
