           Summary: Allow loading file:// resources that have no referrer
           Product: WebKit
           Version: 420+ (nightly)
          Platform: PC
        OS/Version: Mac OS X 10.4
            Status: NEW
          Severity: Normal
          Priority: P2

Currently loading file:// resource that doesn't also have file:// referrer will
fail because FrameLoader::canLoad() returns false.

That means that unless special steps are taken in the upper layer to fake a
file:// referrer, loading a file:// resource given e.g. in a command-line or
entered directly in the url bar will fail. It certainly does in gdk build since
all it does is Frame::loader()::load(url) which ends up passing an empty string
as a referrer to FrameLoader::canLoad().

For gdk build it's a regression because it used to work. I tried to track down
the change that might have caused that but failed (too many changes to
FrameLoader.cpp).

The fix is to change FrameLoader::canLoad() to return true if url is a file and
referrer is an empty string.
