v3 keys are evil
----------------
-The good thing about v4 keys is that the fingerprint ends contains the 8 byte
-(16 char) key id at the and and that the 8 byte key id likewise ends in the 4

-servers make the handling of v3 a PITA.

The key will be imported from the keyserver, but caff thinks it failed. Now run
caff again with -R:
