I don't think you could call it a bug. Maybe a carbon based error! The
problem is that you are midway through a command and emacs is waiting
for data to be entered in the minibuffer. When you try to execute a
second C-x C-f, emacs tries to use the minibuffer again, but its
already in use by the previous find-file command. 

I think the issue is that while emacs has multiple frames, there is
really only one minibuffer - each frame doesn't have its own
minibuffer. Essentially, you cannot use a command which requires the
minibuffer when your half way through executing a command which is
already using the minibuffer. You would probably be able to use any
command in the second frame which does not require the minibuffer
without problems.
