bug#4866: Buffer list in Buffers menu is not updated on the fly

[Robert Jørgensgaard Engdahl]

The problem startet right after upgrading from Ubuntu 9.04 to Ubuntu
9.10.  When starting emacs for editing a file, like

$ emacs Makefile

and then later do "C-x C-f something.mk" to open the file called
something.mk, the something.mk is not added to the list of buffers in
the Buffers menu.

Furthermore, when closing the Makefile buffer, Makefile is not removed
from the buffer list in the Buffers menu.  And when choosing Makefile
in the buffer list in the Buffers menu I get the error

 <menu-bar> <buffer> Makefile is undefined


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/share/emacs/22.2/etc/DEBUG for instructions.

This is a known issue, fixed in Emacs CVS.

As a workaround, you may use

GDK_NATIVE_WINDOWS=1 emacs
