Ok, here I triggered a problem: I used C-h k (with the new help.el)
followed by a mouse-2 click on an overlay's 'before-string which has
its own 'keymap and 'display properties (the string, not the overlay).

I get

Debugger entered--Lisp error: (args-out-of-range 806 806)
  key-binding([(mouse-2 (#<window 41 on ang.tex> 806 ... -61397984 ... 806 ... ... ... ...))] t)
  describe-key([(mouse-2 (#<window 41 on ang.tex> 806 ... -61397984 ... 806 ... ... ... ...))] 1 nil)
  call-interactively(describe-key)

It would appear that 806 is the buffer position, and I would guess
that this is erroneously used as in index into the before-string
property of the overlay.
