23.0.60; Segfault after mouse-drag-region

[Stephen Berman]

I was using the mouse to copy text from an Emacs buffer (URLS from an
emacs-w3m buffer) to an external application, and after doing this a
number of times without a problem, suddenly Emacs crashed.  I was not
running it under gdb but did get a core dump.  The output of `bt full'
on the core file is appended below.
