Description:
Depending on the locale settings, some font families are not recognized and fonts are not properly conflated into one entry in the font list of libreoffice.

Tested on multiple Ubuntu machines. See screenshots for configuration details.

Steps to Reproduce:
For Ubuntu Linux:
install libreoffice and libreoffice-l10n-de

Then start, e.g., loimpress with either 
LANG="en_US.UTF-8" loimpress 
or with 
LANG="de_DE.UTF-8" loimpress

Actual Results:  
If I start LibreOffice with LANG=en_US.UTF-8, the font  "Latin Modern Sans" is shown as "LM Sans 8", "LM Sans 10", and so on. This list is very long and not helpful!
If I start LibreOffice with LANG=de_DE.UTF-8, the font shows up as "Latin Modern Sans" (as intended).

Expected Results:
Independent of the language settings, the font should always display under this name. 


Reproducible: Always


User Profile Reset: Yes



Additional Info:
This is very annoying if you work in an international team and use such a font. It may probably also be connected to some other bugs that I have seen here, e.g., 69881, 72938, 72944, 77910, but please not that this bug is most definitely *not* a duplicate of any of those.

What did not fix this:
- fresh user profile
- reinstall font files
- update font cache (fc-* commands)
