Keyboard switcher sometimes reset both layout switch and compose settings to <none> upon session start. Also, closing this applet causes a 1-2 minute long delay.
Confirm on Fedora 15 x86_64 Also, when I open "Applications Menu/Preferences/Keyboard" and choose "Layout" (sometimes) it brings "Keyboard Layouts" list back to the settings ("Change layout option" remains empty).
Should be fixed in git master branch, feel free to reopen if it still happens.
