[h-e-w] EmacsW32: Unable to save (sporadic)

[Jonathan Roes]

Hi emacs-windowsers,

Sometimes when I try to save with C-x C-s (and also manually with M-x
save-buffer), I get an error the following error in the minibuffer:

(wrong-type-argument number-or-marker-p nil)

With the debugger enabled, I get the following:

Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)
  min(nil nil)
  apply(min (nil nil))

I haven't been able to pinpoint an exact sequence of steps or quite
yet, but this happens frequently enough to really give me problems
working.  I'm using the patched 20080602 EmacsW32 build from the
EmacsW32 site.

Anyone else running into this problem and/or have a fix?
