I tried reproducing this, but couldn't.  I guess your case has some
hidden aspects.  So:

  . does this happen in "emacs -Q"?
  . if it does happen in "emacs -Q", please set debug-on-error to a
    non-nil value, run the command to get a backtrace, and post the
    backtrace here
  . if it doesn't happen in "emacs -Q", please try to find the
    customization that causes this

The bug report seems to indicate that the problem happens in the
process-sentinel:

  error in process sentinel: Wrong type argument: integer-or-marker-p, nil [2 times]

but it doesn't give enough details to investigate further.
