I don't see any problems with quoting or parentheses in the parts of
the code you're showing us, but they may be present elsewhere.

If you step the function in debugger (see ?debugonce and ?browser),
does it crash in the call to cat()?

If you take your function apart by applying as.list(body(fun)) (and
furthermore applying as.list() to any parts of the function), do you
see the call to cat() taking exactly the arguments you mean it to take?
