Signed but not encrypted messages are marked "invalid digital signature"
When receiving signed but not encrypted messages, thunderbird complains with "invalid digital signature" and "technical error deteced". Unpacking the message and checking with gpg manualy verifies the signature correctly. Messages encrypted and signed are verified correctly. When looking at the logs in the console, I can see:

Does simply singing without encryption require some special settings?

I try not to follow PGP. But I am aware various libraries supports all sort of broken and obsolete signature files that the library in Thunderbird does not.
Have you considered posting your request in the encryption list where those that have an interest can be found as discussed in the end to end encryption user documentation https://support.mozilla.org/en-US/kb/introduction-to-e2e-encryption#w_discussion-and-support.?
Hm, looks more like a TB than GPG issue to me. Anyway, opend a new issue at https://thunderbird.topicbox.com/groups/e2ee . Thanks.
