            Bug ID: 112088
           Summary: PPTX with specific gradient fill opens with repair in
                    PowerPoint after roundtrip
           Product: LibreOffice
           Version: 5.0.0.5 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Keywords: filter:pptx
          Severity: normal
          Priority: medium

Sample PPTX (becomes corrupted after roundtrip)

The attached presentation contains a single shape with a gradient fill where
the two gradient stops are at the same position.
Save it as a new PPTX in Impress. The resulting file opens with repair in
PowerPoint.

Note that if one of the gradient stops is moved even by 1%, the roundtripped
file opens fine (the colors are flipped, though).
In Impress the gradient shows very differently in both cases, possibly due to
bug 76682.

Observed using LO 6.0 daily build (2017-08-27_23:19:54,
9600f5179795380749aa5a7c9fa0bf5387d2b95f), 5.0.0.5 / Windows 7.
