Hi,

Due to how the KDE proxy config module works the value for the "Proxy Config Script" in kioslaverc may be a URL but also may be a local path (like /home/user/foo) without a scheme prefix.

libproxy seems to only handle the URL case correctly. If the scheme is missing it seems to put the path into g_uri_parse() in px-manager.c, which apparently results in an invalid object and it is ignored.
