Binding backspace key while using screen

[Jacek Masiulaniec <spam@xxxxxxxxxxxxxxxxx>]

Hello,

I'm having problem using mutt + screen. I don't know whether it is a mutt or
screen problem, but I decided to ask here.

I've bound a backspace key to a previous-line function in my .muttrc like
this: 

bind pager "<backspace>" previous-line

But, unfortunetaly, it doesn't work. :( Well, it works under a normal
terminal, but in screen it fails - mutt says that key is not bound. I'm
using screen 4.0.1, mutt 1.4.1 and ncurses 5.3. All of these are built by
myself, I'm using some kind of LFS system. Here is the result of 'ldd
/usr/bin/mutt' (just to avoid confusion):

        libncurses.so.5 => /lib/libncurses.so.5 (0x40019000)
        libc.so.6 => /lib/libc.so.6 (0x4005a000)
        libtinfo.so.5 => /usr/lib/libtinfo.so.5 (0x4017d000)
        libgpm.so.1 => /usr/lib/libgpm.so.1 (0x401a6000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

Any help would be appreciated,

Regards,
