           Summary: [Qt] Regression: Fix for 49650 breaks custom QNAM
                    implementations...
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebKit Qt
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: adawit at kde.org


The fix applied to workaround the QNAM limitation in bug 49650 breaks custom QNAM implementations, namely kdewebkit's, that rely on the unsupportedContent signal being invoked as soon as possible instead of being queued. 

kdewebkit requires this functionality in order to take advantage of KIO's put-slave-on-hold functionality which allows two different applications to share the same network resource. That way a single resource will not be downloaded multiple times: once when the user clicks on the link and a second time when the appropriate application attempts to display the resource.
