[Message part 3 (text/plain, inline)]

When I try to C-x C-f a file the file opens but the buffer isn't brought
to front. Instead, the frame is split. Apparently, it is because of
the following error message:

vc-find-file-hook: Wrong type argument: stringp, nil

The full *Messages* log since start of Emacs is following:

Removing Mtn from vc-handled-backends "fixes" the problem.
