ibuffer's "s v" doesn't redraw buffer

[Eric Hanchrow]

* I started emacs with "emacs -Q"
* I loaded ibuffer: M-x load-library<return>ibuffer<return>
* I ran ibuffer: M-x ibuffer<return>
* I sorted the buffer by major mode: s m

I note that after I type the "m", the buffer is immediately redrawn,
with the entries in their new order.

* I sorted the buffer by recency: s v

I note that the buffer hasn't changed.

* I force the buffer to change: g

Now the buffer looks the way I'd expect it to.
If emacs crashed, and you have the emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/local/src/emacs-cvs/etc/DEBUG for instructions.
