Powerpoint file, which when opened in impress, demonstrates corrupted motion path animation

Description of problem:
Opening a pptx file in libreoffice impress, containing a motion path animation created in powerpoint 2010 (and other versions), results in an animated motion path with a corrupted start point.

How reproducible:
Always. This has been a long term issue.

Steps to Reproduce:
1. Create new pptx file
2. Add an object (e.g. rectangle)
3. Create a motion path animation
4. Save file
5. Open in impress

Actual results:
In the case of the attached example, the motion path has the correct end point, but the starting point is not within the object, but rather far off the screen.

Expected results:
The same motion path that was created in powerpoint should appear in impress.

Additional info:
The external bug from freedesktop.org seems (#33852) seems to report a similar issue with ppt files, though the way in which the path is corrupted appears to be slightly different.
