           Summary: [Qt] Initialize HTML5 Application Cache for QtWebKit
                    to a sensible default
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebKit Qt
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: laszlo.1.gombos at nokia.com


QtLauncher is crashing if a page with HTML5 App Cache is visited. This is
because the app cache is designed so that
WebCore::cacheStorage().setCacheDirectory() needs to be called with a path
before the app cache can be used.

As far as I can tell QtWebKit does not call
WebCore::cacheStorage().setCacheDirectory to set the path for the app cache
neither provides a public API for QtWebKit clients to set the path; the closes
I found an internal API called
qt_websettings_setOfflineWebApplicationCachePath() which indeed can be used as
a work-around.

As I first step I would like to propose that QtWebKit would set the app cache
path to a sensible default so that QtWebKit clients does not have to deal with
the issue. Later we might want to revisit how can a client set the path puth a
public APi if there is a need for that.
