That was first thing I tried. Tried to add g_setenv("XDG_MENU_PREFIX", "gnome-flashback-", TRUE); in two different places:
1) In gnome-panel/main.c in main() function.
2) In gnome-panel/libpanel-util/panel-launch.c to set env variable when launching desktop files.

In both cases env variable was not updated.
