Additional note I don't think it's related, but I've built ghc-mod with -fPIC because of build issue occuring on arch linux.

It's nothing major. ghc-mod can't handle browse Main, so Main is filtered out of arguments list. In case argument list ends up empty as a result, this happens. Since there was nothing to browse anyway, it doesn't break anything really, but I guess can be annoying.

Anyway, should be fixed in v2.1.3
