Backtrace in splash screen

[David Kastrup]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I called up the splash screen with the Help/About Emacs entry.  When I
next moved the mouse over the "Help" menu entry, when it should be
giving a tooltip, it instead barfed with
