Slightly OT: PGP/MIME verification fails with new KMail2 and Thunderbird 13.0

[Hauke Laging]

Hello,

I was just pointed at the problem that for the last months all of my 
signatures are supposed to be bad. I use KMail which shows both the emails I 
have sent and those I receive via this list as correctly signed. I just used 
Thunderbird (13.0) to check and TB claims even (most but not all) of the 
emails in my IMAP sent folder to have bad signatures. TB doesn't even 
recognize the received emails as signed (just shows an "attachment").

The problem seems to be newline-related. I do not waste time by filing a bug 
report for the wrong software... Thus maybe one of the MIME experts here can 
tell me who's wrong. The KMail behaviour seems to have changed from KMail to 
KMail2. KMail2 successfully verifies the TB emails.

Thunderbird puts one more empty line between the body and the MIME seperator:

I can manually successfully verify emails from both clients. So obviously one 
of them feeds the wrong data into gpg (during signing or verification).
