           Summary: image viewer doesn't support Windows BMP with negative
                    height (top-to-bottom [reversed] line order)
           Product: kde
           Version: unspecified
          Platform: Debian stable
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs kde org
        ReportedBy: kde csmiller demon co uk


Version:            (using KDE 3.5.8)
Installed from:    Debian stable Packages

says this
  Width and Height are the width and height of the image in pixels,
  respectively.  If Height is a positive number, then the image is a
  "bottom-up" bitmap with the origin in the lower-left corner. If
  Height is a negative number, then the image is a "top-down" bitmap
  with the origin in the upper-left corner. Width does not include any
  scan-line boundary padding.

Both konqueror in ViewMode->photobook, and KImageMap editor 
display a black square when the height is negative.

This is probably a bug in a common library, possibly in QT.
