When opening it in OpenOffice, I instead get this less helpful message:Lesefeil.
Fann formatfeil i fila i underdokumentet content.xml ved 2,136719(row,col).
Reading error.
Found formatting error in the file in the subdocument content.xml at 2,136719(row,col)
This is despite trying previous backups of the file. When opening the most recent file, it references 2,136719(row,col), which is the same as when opening the version from yesterday evening and morning, as well as the file from two days ago. Were it just the latest version, it would have made at least a little bit of sense, but that the backups all of a sudden are unreadable as well – that is file versions which I have previously worked on and saved – leaves me clueless as to what is causing this.Lesefeil.

And finally, I forgot to mention, I repaired my LibreOffice installation (in case that might be the problem) and did a clean new installation of OpenOffice; neither of these actions had any effect on the result.
