           Summary: KURL's getters are inconsitent about returning null or
                    empty strings
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Platform
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: brettw at chromium.org


KURL's getters randomly return either isNull or empty strings. This is
potentially dangerous if some code relies on this.

Returns a null string on empty:
  pass()
  lastPathComponent()
  ref()

Returns an empty string on empty (although at least some of these will return a
null string if the URL is itself null):
  protocol()
  user()
  host()
  query()
  path()

We can make them all return null strings, all return empty strings, or return
null strings only when the URL is itself NULL, and empty the rest of the time
(I think this is currently the dominant behavior).
