smart 0.50rc1-7 ok @ shell, GUI fails

[snowcrash+smart]

i've installed on opensuse 10.1,

	smart-beta-0.50rc1-7.guru.suse101 at i686
	smart-beta-addons-0.50rc1-7.guru.suse101 at i686
	smart-beta-gui-0.50rc1-7.guru.suse101 at i686

i've been using it from shell for a bit.

when i just tried to start Smart from the SuSE desktop -- nothing happened. :-/

so, checking from console,

	smart --gui

reports,

checking in,

  ls /opt/gnome/lib/gtk-2.0/2.4.0/loaders/
