DKIM can not be verified on some emails (4.1.0)

[xsistema]

Just installed 4.1.0 version on Win10 64-bit, and noticed that DKIM can not be verified on some emails (DKIM label is blank). Error:

Thanks for reporting. Unfortunately don't see what could actually go wrong.

The only error I see in the log you posted is Promise rejected after context unloaded: Actor 'Conduits' destroyed before query 'RuntimeMessage' was resolved. But for code that:

• Did not change in 4.1.0 (compared to 4.0.0)
• Is for the popup in the DKIM button of the email header. It should not run unless you open the popup and click a button.

Could you please try/answer the following:

• Does the error still occur after a restart of Thunderbird?
• Does it always happen with the same messages?
• Which Thunderbird version are you using?
• Which addon version there you using before?

After restarting TB 97.0b3 - problem disappeared. But if email does not contain DKIM signature - the line is blank, though occupies some vertical space. Is it by default? I think it should be a message - no DKIM or similar. At error console:

DKIM_Verifier.AuthVerifier DEBUG AuthResult result found: {"version":"3.0","dkim":[{"version":"2.0","result":"none"}]}

[lieser]

No, the blank line is a bug in the addon. Unsure if that is something new, or if I missed it in TB 96. Should be fixed now.

Will wait with releasing a new version in case more bugs are reported. Attached a new version here.
