Description Tobias Leupold 2014-04-29 10:44:14 UTC 
There seems to be a problem with PGP signature verification.

I recently got two emails that have been signed with a PGP key. For both, kmail states that the signature was invalid. One was from the German department for security in information technology, one from the PGP global directory verification service. I'm pretty sure those don't generate emails with invalid signatues.

In contrast, when I send an email to my own email address, signed with my owm PGP key, kmail confirms it's validity.

I'll attach the respective emails for debugging (nothing private in it ;-)

Reproducible: Always

I believe I had stumbled on the same problem of changing the layout of the messages, see

HTML email that is incorrectly reported as invalid

I'm attaching another email. It verifies correctly in all programs except KMail. E.g. both Thunderbird and Evolution report a valid signature.

I can confim it with 4.13 and 4.14
