           Summary: [Qyoto][PATCH] QApplication constructor crashes when
                    run through NUnit
           Product: bindings
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kde-bindings at kde.org
        ReportedBy: tobias.kappe at gmail.com


Version:            (using KDE 4.3.3)
OS:                Linux
Installed from:    Ubuntu Packages

When the constructor for QApplication is called through NUnit (for example,
when initialising Qt in TestFixtureSetup to test dialogs), it throws a
NullReferenceException. This is caused by
System.Reflection.Assembly.GetEntryAssembly() returning null.

To work around this, System.Reflection.Assembly.GetExecutingAssembly() could be
called when the call to GetEntryAssembly fails. A patch is included that
provides for this. Also, somewhat redundant code has been factored out.
