Hello.
I was accepting some suggestion 3 days ago, and I wanted to copy them to
the master branch by downloading each and running a script on them. I
noticed then that the "system user" user did overwrite on all of them with
empty translations! Is that normal? If not, then what would be the problem?

Language: Arabic
Folder: LibreOffice 5.0 - UI (sw/uiconfig)
