When I upgrade to lxsession 0.4.9 (compiled .2 this morning) I am unable to login to my Fedora 17 (x86_64) LXDE desktop. It immediately returns to the login screen. The 'run.log' give plenty of errors, but I am having a hard time interpreting those. Deleting /etc/xdg/lxsession/LXDE/autostart has no effect.
lxsession 0.4.6(.1) works fine.
