Thanks!

I would expect the completion UI to show a message, instead of an error
from the Capf. For example if you start emacs -Q, type "nonexistent
M-TAB" in the scratch buffer to access the normal Elisp completions.
Then you will see the message "No match" in the minibuffer. If
`dabbrev-capf' would not throw an error, we would get the same message.
