           Summary: [Qt][Wk2] Assertion Failed and crash on file upload
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit2
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: dinu.jacob at Nokia.com


Using MiniBrowser,

1. Load http://iop4.nokia-boston.com/users/tests/fileupload/fileupload.html
2. Click on "Browser" to upload a file

This causes an ASSERT:
ASSERT: "!fileDialog" in file Source/WebKit2/UIProcess/API/qt/qquickwebview.cpp, line 386

Attempting to upload a file after fixing the ASSERT resulted in crash:
QWidget: Cannot create a QWidget when no GUI is being used

Program received signal SIGABRT, Aborted.
