bug#70760: 29.3.50; core dumps when copy in other apps

[Kun Liu]

I did (setq debug-on-error t), went to https://en.wikipedia.org/wiki/Emacs, randomly selected a fragment "Emacs has over", then did a ctrll+c.

Emacs in VirtualBox immediately showed the following:

Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)
  dbus-handle-event((dbus-event "[ \11]*$"))
  funcall-interactively(dbus-handle-event (dbus-event "[ \11]*$"))
  call-interactively(dbus-handle-event nil [(dbus-event "[ \11]*$")])
  command-execute(dbus-handle-event nil [(dbus-event "[ \11]*$")] t)

What were you copying in Chrome when this happened?  Was it text or
some other entity.  Does the text/object you were copying have
anything in common with the data of the error message above?  Can you
tell what URL to go to and which part of the page to copy, to
reproduce what you did?

Also, please set debug-on-error to a non-nil value, and post the Lisp
backtrace you get when these errors happen.
