And why would that be a Thunderbird problem? How do you do DKIM validation?

[e-mail] could be Philippe Lieser, author of DKIM Verifier. Otherwise, please excuse me.

Yes, I'm the author of the add-on DKIM Verifier. An I agree with Joug, if the error you reported is about the add-on, this is probably the wrong place to talk about it (see https://github.com/lieser/dkim_verifier/wiki#support-and-bug-reports for alternatives).

If the problem is about the add-on, I would need more info, as I could not reproduce it. It could also be simply your receiving e-mail server, which is changing the encoding and therefore breaking the signature (You would not be the first to encounter this).
You could try a different local DKIM verifier (e.g. https://launchpad.net/dkimpy, available in the python-dkim package in debian and ubuntu) to see if it comes to the same result. Also try to send the e-mail to a different receiving server, which is not know to cause any problems (e.g. gmail) (best send one single e-mail to both you normal server and a gmail address, and compare the sources of both received e-mails).
