           Summary: drag gesture can cause WebKitGTK to take mouse grab
                    indefinitely
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Major
          Priority: P2
         Component: WebKit Gtk
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: grant_gayed at ca.ibm.com


- using WebKit 1.1.16 built from source on Ubuntu 9.10

- run the GtkLauncher app and navigate to a page that shows a static image
(eg.- the banner at the top of
http://www.slis.indiana.edu/faculty/hrosenba/www/Demo/Demo5.html )
- click quickly and repeatedly on the image while moving the mouse a little
bit, and you'll soon (within a few seconds) get into a state where WebKitGTK
has taken mouse grab and there's no way to get it to let go
- additionally, when this happens the following is written to stdout:

(GtkLauncher:22437): Gdk-CRITICAL **: gdk_window_get_events: assertion
`GDK_IS_WINDOW (window)' failed

(GtkLauncher:22437): GLib-GObject-CRITICAL **: g_object_ref: assertion
`G_IS_OBJECT (object)' failed

(GtkLauncher:22437): GLib-GObject-CRITICAL **: g_object_unref: assertion
`G_IS_OBJECT (object)' failed
