At: https://pontoon.mozilla.org/kab/mdn/LC_MESSAGES/django.po/?string=141801 the English string: "Found %(count)s documents." has been translated to "%(num)s n isemliyen yettwafen." Changing the variable from "count" to "num" breaks string compiling.
Thanks for approving my suggested string Belkacem.
Locale tests pass. Thank you for the quick fix!
