A Debian user has submitted the following bug. Details are at
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=198932 :

I have the emacs shortcuts selected in my gnome desktop preferences, as
well as in my .gtkrc-2.0, and most shortcuts work well in the message
editor. However, two core emacs keybindings are overridden in the menus
(Ctrl-E and Ctrl-W). Every time I run pan, the first time I post a
message, I need to hover over the "Edit with external editor" and
"Close" menu items and press backspace to get them to work properly. 

I tend to believe this is actually a problem in the way accelerators are
designed in gtk2 because other apps suffer from this (evolution1.4 comes
to mind), but I don't think it'll be fixed there, so I am reporting bugs
against each app that suffers from the problem.
