Does it look like this in the minibuffer?
 Describe key (or click or menu item):  C-)-
IOW, ending with a with a dash, with the cursor after the dash?

If it does, that's a sign that `C-)' is defined as a prefix key, for some
reason. `C-h k' waits for the rest of the key sequence following the prefix.

You can try this, to try to get some more info: `C-) C-h'. With a little luck,
if `C-)' is in fact a prefix key this will show you help about `C-)' and its
possible completions. The command names bound to the keys might give you a clue
about what library is binding `C-)'.

You say that this also happens to you if you start Emacs using `emacs -Q'? If
so, then consider filing a bug: `M-x report-emacs-bug'. AFAIK, `C-)' should not
be bound to anything by default in virgin, vanilla Emacs. (describe-key (kbd
"C-)") should say simply `C-) is undefined'.

If this same behavior does not occur with `emacs -Q', however, then look in your
init file for something that is defining `C-)' (as a prefix key). To find it,
use binary search: comment out half your init file, then half of that, and so
on, until you narrow down the guilty part. Sounds long, but it's actually very
quick to do.

What does that help say? If it says `C-) is undefined', then there is likely a
problem with `describe-key'. If it gives some command name, then take a look at
the library that defines that command.
