Created attachment 122899 [details] Possibly broken file A customer of mine sent me a bunch of DOCX files which apparently are broken: on Windows I tried LO 4.4.7 and LO 5.0.5, but even MS Office 2010 won't open them. What surprised me is that both LO 5.0.5 and OpenOffice 4.1.2 were able to open all of them without any trouble on FreeBSD. I'm attaching a sample in case someone is interested in checking it.
MS Office 2010 and 2016 can't open it, no point in further investigation.
