ooo24358-1.ppt
The attached PPT presentation, ooo24358-1.ppt is from an old AOO bug report.
After converting to PPTX with Impress, PowerPoint fails to open it, and tries
to repair the presentation.
OOXML-Validator gives the following result:
[{"Description":"Relationship tag requires attribute 'Target'. Line 2, position
86.","Path":null,"Id":null,"ErrorType":"OpenXmlPackageException"}]
This is the same error, as in bug 168736, and at first glance, the cause is the
same:
- in ppt/slides/_rels/slide1.xml.rels, multiple entries with empty targets:
<Relationship Id="rId1"
Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/slide";
Target=""/>
- ppt/slides/slide1.xml, link elements like this: <a:hlinkClick r:id="rId1"
action="ppaction://hlinksldjump"/>
But not exactly, in PowerPoint, the red dots have hyperlinks leading to '#2.
Custom Topic A' that doesn't exist in the presentation, and the hyperlink is
removed when saved to PPTX in PowerPoint. In Impress the target becomes 'Slide
2', which also doesn't exist, and is then exported incompletely.
This used to be dropped in Impress, but from the following commit in 7.3, it
survives the roundtrip:

"tdf#144914 PPTX export: fix interactions and hyperlinks on shapes"
I think it's reasonable to remove hyperlinks that lead nowhere within the file.
