Broken app

STEPS TO REPRODUCE
1. Run Discover in any Arabic language (e.g. `LANG=ar_AR plasma-discover`, `LANG=ar_OM plasma-discover`, or `LANG=ar_EG plasma-discover`


OBSERVED RESULT
App's layout is broken and unusable; see attached screenshot.

There's a log flood of the following repeated messages:

EXPECTED RESULT
Everything works.


ADDITIONAL INFORMATION
Works with Hebrew (`LANG=he_IL plasma-discover`) so it's not happening for all RTL languages. Other Kirigami-using apps work with Arabic languages; only Discover is affected.
