using gnucash 1.8.1, gnome-libs 1.4.1.7.

in gnucash 1.6.x i could bind keystrokes to menu items in a register window
in the normal gnome fashion, by highlighting the menu item and pressing the
key combination.

i upgraded gnucash to 1.8.1 and all my bindings were lost.  if i try to
bind a key to a register menu item now, that binding is lost as soon as i
close the register window, i.e. it is no longer in force next time i open
that or any other register window.

if i open two register windows concurrently and bind the key in one, it
does not take effect in the other.

finally, if i try to re-bind the same key to another menu item, or try to
bind it to the same menu item in another window, i cannot; instead the
associated action takes place in the window where it was associated, even
if that window does not have focus.

for example, i like to bind ctrl-z to `actions/blank'.  if i make that
binding in register window #1, and subsequently highlight another menu item
and press ctrl-z (with the intention of changing the binding to that menu
item), register window #1 jumps to the blank transaction.  if i then open
register window #2, highlight the action/blank menu item (or any other menu
item) there, and press ctrl-z, register window #1 again jumps to its blank
transaction.  if i then close register window #1, i can bind ctrl-z in
register window #2 normally.  finally, once i close register window #2, the
binding is lost until next time i bind it somewhere.

i am using the same version of gnome-libs as i was before i upgraded
gnucash.  also, bindings work fine in the main accounts window, and persist
normally across quitting and re-launching gnucash.  finally, gnome
keybinding still works normally in every other app that supports it.  so i
don't believe this is a bug in gnome-libs.
