Uh oh.
b40-pre1 has become b40-pre2 with three fixes:
man/lispref/dragndrop.texi is included
apropos.el has a (concat integer ...) fix
`with-displaying-help-buffer' has been reverted to its 20.4 interface
None of these changes are likely to fix this crash. :-(
I'm rebuilding now with lisp unions and full error checking and will
see if I can spot anything.
