1. emacs -Q
2. Eval this:
(defun testme ()
(save-selected-window
(switch-to-buffer "testme")))
If `testme' is not a fresh buffer, see observation (a) below.
3. Eval (run-at-time 3 nil 'testme) and wait 3 seconds.
4. When the `testme' buffer appears, move the mouse cursor over the mode line;
as soon as it hits a position that has a help-echo property containing the
string "mouse-2", the following error is raised:
mouse-posn-property: Args out of range: 719
The out of range number is (point) in step 3.
Backtrace:
Debugger entered--Lisp error: (args-out-of-range 719)

mouse-fixup-help-message("mouse-1: Select (drag to resize)\nmouse-2: Make
current window occupy the whole frame\nmouse-3: Remove current window from
display")
Observations:
a. The error only occurs when (point) of the the buffer that is current when
step 3 is carried out, is greater than (point-max) of the buffer `testme'.
b. The error only occurs when testme is called from a timer.
c. The error only occurs when the function called from the timer
contains a call to save-selected-window.
d. The error only occurs with propertized text satisfying mouse-on-link-p in
either the mode line or the header line, i.e., suitably propertized
text inserted into the editing area of the buffer does not induce the
error.

I've checked in a fix. Thanks.
