[Ivan Kanis]

This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgement at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

1) emacs -Q
2) M-x toggle-debug-on-error
3) M-x calendar

Debugger entered--Lisp error: (void-function window-combination-p)
  window-combination-p(#<window 7> nil)
  calendar-generate-window(11 2011)
  calendar-basic-setup(nil)
  calendar(nil)
  call-interactively(calendar t nil)
  execute-extended-command(nil)
  call-interactively(execute-extended-command nil nil)

This breaks org scheduling with is very annoying.

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'.

I can't reproduce this. The function window-combination-p is no longer
anywhere in the Emacs sources.

I had a variant of this issue today: every use of any "electric"
function from ehelp.el caused the error about window-combination-p.

I suppose there are some elisp files that require recompilation. I
cured it by bootstrapping.

Indeed bootstrap cures it, in the future I'll bootstrap before reporting
a bug...

Debugging is twice as hard as writing the code in the first place.
Therefore, if you write the code as cleverly as possible, you are, by
definition, not smart enough to debug it.

Not always needed, but sometimes it's the easiest way to "cure"
problems when functions or variables have been removed.

I'm closing this bug.
