What mode was the buffer in (c-mode)?  Might you have been in
text/fly-spell or something similar?

My gripe is that fly-spell and some other new-fangled sub-modes add
some context-sensitive bindings.  If you want to try to hit C-c C-c to
send a message from "mail-mode" while over a word that fly-spell
doesn't like it grabs the C-c's on you and you don't get the action
you expect.
