Description:
When trying to open a file which is already open in another program the resulting "file in use" prompt (the one which asks how the user wants to open the file) is not fully localised in the user's language.

As per the attached screenshot, the "open as read only" and "open copy" buttons are in English, while they should be in Italian (the language I'm using LO in).

LO components I have tried this with:

- Writer, by opening a docx file with Microsoft Word and then Writer;
- Calc, by opening an xlsx file with Microsoft Excel and then Calc;
- Draw, by opening a PDF file with Adobe Acrobat and then Draw.

I haven't tried Impress and Base, but they're presumably the same.

Steps to Reproduce:
1. Open a file with a program that is not LibreOffice;
2. Do not close the file;
3. Open the same file with LibreOffice.

Actual Results:
"Open as read only" and "open copy" buttons are in English.

Expected Results:
"Open as read only" and "open copy" buttons are in Italian.


Reproducible: Always
