           Summary: WebKit2GTK - WebKitWebProcess assertion fails when
                    dragging and dropping a file into the view
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: Daniel.Wyatt at gmail.com

Epiphany and Midori both crash WebKitWebProcess (assertion fails) when dragging and dropping a .html (or other) file into the web view.
This only happens if we have not previously opened a .html file through the menu.
I've tested this with SVN 162714.

In WebProcessProxy::checkURLReceivedFromWebProcess I see:
    // Any file URL is also OK if we've loaded a file URL through API before, granting universal read access.
    if (m_mayHaveUniversalFileReadSandboxExtension)
        return true;

Are Epiphany and Midori are just doing something wrong (failing to grant universal read access somehow)?

Output from a release build:
Received an unexpected URL from the web process: 'file:///home/daniel/tmp.html'
Received an invalid message "WebPageProxy.DecidePolicyForNavigationAction" from the web process.

Output from a debug build:
Received an unexpected URL from the web process: 'file:///home/daniel/tmp.html'
Received an unexpected URL from the web process: 'file:///home/daniel/tmp.html'
ASSERTION FAILED: m_process->checkURLReceivedFromWebProcess(request.url())
