           Summary: [BlackBerry] Fix undesired re-entrant calls during
                    media error dialog
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit BlackBerry
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mfeil at rim.com


A recent change in libwebview/fe1e943 to the dialog handling means that dialogs are not truly blocking anymore. While the dialog is up, a sub-event loop is called. Therefore the HTML5 media code will continue processing pps messages from mm-renderer, responding to periodic timers, etc., all while a media error dialog call higher up in the stack is waiting for the user to respond. Unfortunately some places in our code do not anticipate being called in a re-entrant way.

This patch restores behaviour to how it was previous to libwebview/fe1e943.
