bug#1930: 23.0.60; Can't jump to error location in compilation-mode

[Magnus Henoch]

After running a compilation with M-x compile, I try to jump to the
location of an error with M-g M-n.  This doesn't work, though:

Debugger entered--Lisp error: (wrong-type-argument window-live-p nil)
  select-window(nil nil)
  pop-to-buffer(#<buffer erltest> other-window)
  compilation-goto-locus(#<marker at 3465 in *compilation*> #<marker at 1749 in 
erltest> nil)
  compilation-next-error-function(1 nil)
  next-error(nil)
  call-interactively(next-error nil nil)


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/local/share/emacs/23.0.60/etc/DEBUG for instructions.
