I agree that GPG issues are unlikely to happen, but there are some
pitfalls that could become a PITA. For example, a kernel developer
(Mr. Wagner) signed the source of a patch with a sub-key, that isn't
included to his public key available by keyservers. I imported his key
(without the required sub-key ;) from a keyserver, hence I was unable
to verify the kernel patch signed by him. In the end I got the sub-key
by importing it via git from kernel.org.

However, the gpg output I got was misleading. The short of the key is
not equal to the sub-key.

It's a subkey hence the file name wont match. The file name is the
finger print and not the subkey.

ps: I have very strong feelings when it comes to gpg and no they are not
the good ones.
