Display problems in Buffer List

[Michael Welsh Duggan]

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

Using today's CVS, The buffer-list window seems to be screwed up
somehow.  To reproduce:

emacs -q -no-site-file
C-x C-b

At this point, the frame splits such that there is a *Buffer List* in
the bottom window, but there are some problems with it:

1) The scroll bar is not displayed
2) The header is not displayed
3) After a subsequent C-l, nothing is displayed
4) After a subsequent C-x 0, it segfaults with the following
   backtrace:

Program received signal SIGSEGV, Segmentation fault.
