App crashes while closing

Hello,

I'm using XTP in a DLL and my App crashes while closing in CXTPWinThemeWrapper line 106 :

void CXTPWinThemeWrapper::CloseThemeData()
{
    if (m_hTheme && !m_bDllDetached)
    {
        TRY_POINTER_CALL(CloseThemeData)
            POINTER_CALL(m_hTheme);  <== here
        CATCH_POINTER_CALL()
    }

    m_hTheme = NULL;
}
