Subject: [PATCH 2/3] Fix possible crash when passing an invalid PAC URL
This commit checks whether CFURLCreateWithString() succeeded.
It does not appear to be possible to enter an empty URL directly in the
PAC configuration dialog but I can't rule out the possibility
that it could find its way into the settings via some other means.
