The passphrase is asked by an external pinentry application that in turn is 
started by the gpg-agent daemon which is tasked by KMail (through gpgme) with 
signing the mail. I have no idea why you canceling a signing operation should 
have broken signing in general.

As far as I understand, you are no longer asked for a passphrase when you try 
to sign a message. Can you still decrypt encrypted messages? Did you check 
that the correct signing key is set in the settings of your identity? Can you 
sign something with the gpg command line, e.g. by running
echo Hello | gpg --clearsign
in Konsole?
