I confirm it with

I could open file in MS Word 2017

For me it took also to much time to open and save document from comment 1

On Win10 with master sources updated today + enable-dbgutil, I can't even open the initial example file.
At least, after several minutes, it's still not opened.

I noticed these logs which repeat endlessly:
warn:legacy.osl:19480:32484:oox/source/vml/vmlshapecontainer.cxx:45: lclMapShapesById - shape identifier already used
warn:legacy.osl:19480:32484:svx/source/unodraw/unoshape.cxx:1974: SvxShape::GetAnyForItem() Returnvalue has wrong Type!

Same result with

I could finally open the file in Word 2016, but it took a very long time. So for me, the source file itself seems to be problematic and therefor the bug is mor or less document related. So I suggest to close the bug. Telesto, feel free to change it back to NEW with a short reasoning if you disagree and could test it with the latest version of LO.
