lxde-settings-daemon not load default config in /etc/lxde/config if user custom settings (~/.config/lxde/config) not exist!
This cause an error during the start of lxde, my patch resolved this problem fix the read procedure of default config.
pcmanx write to me with:
"I, however, am also working on this part since I'm now trying to merge lxde-settings-daemon and lxsession.
So this patch couldn't be applied, but I'll try to adopt your idea."
Therefore i am not sure to do the right thing posting the patch
