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)
