Here a new window pops up.  Could you please step through the functions
`display-buffer-pop-up-window', `display-buffer-split-window' and
`display-buffer-split-window-1' to find out why splitting a window fails
on your system?

If Emacs can't split a window I currently make a new frame because the
doc-string of `switch-to-buffer-other-window' explicitly says that "The
selected window will be used only if there is no other choice" and
making a new frame _is_ another choice.  If people think that reusing
the selected window is a better choice I can easily do that.

Thanks, martin
