XTP crashes with bitmaps with alpha channels!

I've got several reports that the application crashes after the upgrade to 10.40.

I was able to reproduce the crash and to track it down. It crashes as soon as I add a bitmap (.bmp, not .png) with an alpha channel to the QAT.

It doesn't crash on every PC but I've been able to reproduce it on a clean Win2K SP2 English installation.



In the RibbonSample add a CBitmap m_bitmap; to the CMainFrame class and in LoadIcons add the following lines:

void CMainFrame::LoadIcons ()
{
    CXTPCommandBars* pCommandBars = GetCommandBars();

    HANDLE hBitmap = ::LoadImage (NULL, _T("EditUndo.bmp"), IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_DEFAULTSIZE);

    m_bitmap.Attach (hBitmap);

    UINT nId = ID_EDIT_UNDO;

    pCommandBars->GetImageManager()->SetIcons(m_bitmap, &nId, 1, CSize(16,16), xtpImageNormal, TRUE);
   

    //pCommandBars->GetImageManager()->SetIcons(IDR_SMALLICONS);
....
}

I've attached the modified files as well as the bitmap.
