Created attachment 55801 [details]
original file from wiki page, same file saved with Powerpoint2007 and with LibO

Problem description:
Wiki file from http://wiki.documentfoundation.org/ReleaseNotes/3.5 :
Impress: "Custom Shapes import was greatly enhanced [..]" [..] "Try this example PPTX presentation with slide containing custom shapes identical to presets. In 3.5 it should look like the screenshot above, in the older versions it shows a lot of problems."

This file cannot be opened with Powerpoint 2003 at all. Powerpoint 2007 says it is an invalid XML file created by third party or a deliberately damaged file. After the proposed repair, it displays correctly in PPT 2007 and LibO 3.5 Beta3.

Attached files:
1. Cshape-all.pptx (original file from the Wiki page, can be opened with LibO 3.5 Beta3, with Powerpoint 2007 only after repair)

2. Cshape-all_PPT2007.pptx (file repaired with Powerpoint 2007, can be opened with Powerpoint 2007 and LibO 3.5 Beta3)

3. Cshape-all_PPT2007savedWithLO.pptx (repaired file saved with LibO; is much smaller, cannot be opened with Powerpoint 2007 at all (not even repaired); can be opened with LibO 3.5 Beta3, but all those wellow boxes are empty).

Same result result if file 1 is opened with LibO and saved as Powerpoint 2007/2010 file.

Steps to reproduce:
1. save file 1 with LibO 
2. open resulting file with LibO

Current behavior: file damaged when saved with LibO

Expected behavior: file can be opened with Libo 3.5 and Powerpoint

Steps to reproduce 2:
open file with Powerpoint (no valid Powerpoint file); please replace the wiki file with a repaired one

Reproduced with

LOdev 3.5.0rc1
Ubuntu 10.04.3 x86
Linux 2.6.32-37-generic Russian UI

Open Cshape-all.pptx, resave as .pptx, open - all shapes are yellow squares.
Not checked with PowerPoint.
Comment 2 A (Andy) 2013-04-20 22:34:33 UTC
reproducible with LO (Win7 Home, 64bit)

Result: After reopening it with LO I see only yellow squares and if I try to open it with MSO 2007 that I get the message that the file is damaged and after repairing it I get only an empty slide. -> increased the importance

@Radek: Could this issue maybe be something for you?

I open and save the presentation (and the presentation repaired with MSO 2010) as pptx in LibreOffice 4.3.3 and 4.4.0 beta2 on Debian x86-64. After that I open the saved document in LibreOffice and MS Office 2010 and see the shapes destroyed. They are not squares but completely rubbish.

some tests with with MSO 2016 and LO 6412 x64 in 7z-Archiv

MSO 2016 must repair Cshape-all.pptx after loading.

All C shape pptx saved with have only some artefacts in the elements after save as pptx.

but great improvements against previous tested versions but not perfect.

new save of pptx in odp are ok in first look and have same look like the source.
Comment 8 paulystefan 2020-06-20 18:33:23 UTC
LO 7.0.0 beta2 x64 in Win10 x64

1. solved for me
2. solved for me
3. improved, mostly solved
  some figures are not ok

actual Office 2016 wants to repair this source file also.
so this file is for Microsoft not ok.
