capslock changes control characters?

[Chris Moore]

I tried to insert a TAB into a C++ mode buffer by typing:

  C-q C-i

I got an error:

Debugger entered--Lisp error: (wrong-type-argument char-or-string-p 33554441)
  insert-and-inherit(33554441)
  quoted-insert(1)
  call-interactively(quoted-insert nil nil)

Turns out I had capslock on.  This is reproducible in "emacs -Q" in
the default *scratch* buffer.

$ emacs -Q
[ turn on capslock]
C-q C-i
