Hi everyone,

I have been trying to create a filter for a role on the FactValue resource.
Applying filters with equals operator works perfectly fine, but filtering with a like search raises a "malformed format string - %k (ArgumentError)".
This happens both via WebUI and via hammer.
Here is the stacktrace hammer shows me when updating the filter via "hammer filter update --id <id> --search 'host ~ <name>'":

/opt/theforeman/tfm/root/usr/share/gems/gems/fast_gettext-1.1.0/lib/fast_gettext/vendor/string.rb:70:in `%': malformed format string - %k (ArgumentError)

The same error message (malformed format string - %k) appears in the WebUI when applying a like filter on the facts page in the filter box, or when searching facts via hammer with a like search.

This was tested on Katello 3.1/Foreman 1.12.4, but since I could not find a ticket for this issue, I'm assuming this bug is still around.
