Segmentation fault using Ctrl+o: libgpm related ?

[Frédéric L. W. Meunier <lists1 pervalidus net>]

Hope it helps. Latest CVS on Linux. Compiled with
--enable-charset --with-screen=ncurses --without-ext2undel

How to reproduce it. Start it on a console. It crashes as soon
as you use Ctrl+o. Is it a libgpm bug ? It works fine under
screen, but applications running under it don't have mouse
support through libgpm.

I had used --without-gpm-mouse for a very long time, but
enabled it.
