Bug#949754: libreoffice-writer: cannot open an existing document after an update and subsequent saving (corrupt document?)

[Antonio <antdev66@gmail.com>]

After several tests I found that the problem depended on the
libreoffice user profile of the previous installed version.

To solve this problem I manually removed the file:
$ rm  -f /home/user/.config/libreoffice/4/user/registrymodifications.xcu

which will then be recreated when the program restarts.

In doing so the problem is solved, but the documents saved before this
change are unfortunately no longer recoverable.

Perhaps could be evaluated an action in the installation trigger of
the new version to avoid this eventuality...
