Comment 3 for bug 915273

I've just found a problem. It was caused by incorrect configuration file. Pity that error wasn't really helpfull.

Malformed argument.
Failed to set manual option.
Try `-l manual:help' for more information.

Above error suggest that is a problem with command syntax, not in the configuration file. I think something like

"Error parsing configuration file in ~/.config/redshift.conf" would be better, in case of problems with configuration file syntax.
