You shouldnt have to sign the key, it serves no purpose.  Just mark it
as trusted and you wont get the warnings.  but after all they are just

The key holder should have no problem scraping off junk signatures.  I
hope this is how the WoT works.  They really dont hurt anything, but
that would be a nasty performance hole/exploit to harm the overall
system and create confusion.  easily one could make a key excessively
large and unwieldly.
