           Summary: [Qt] QtWebKit crashes while initializing flash plugin
                    10.1.53.64...
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Major
          Priority: P4
         Component: WebKit Qt
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: adawit at kde.org


With the latest flash plugin viewer from Adobe, v 10.1.53.64, all of the QtWebKit based browsers (including QtTestBrowser) crash when viewing pages that contain flash on my machine. When the SEGFAULT occurs the following critical error message is always printed by the flash plugin on the command line:

(process:9153): GLib-GObject-CRITICAL **: gtype.c:2706: You forgot to call g_type_init()
(process:9153): GLib-CRITICAL **: g_once_init_leave: assertion `initialization_value != 0' failed
(process:9153): GLib-GObject-CRITICAL **: g_object_new: assertion `G_TYPE_IS_OBJECT (object_type)' failed

KHTML, the only other non-gtk based engine I know of, works fine. Anyhow, here is the backtrace:
