Special:Stabilization is a special page created by FlaggedRevs to manipulate the protection settings of a page. That page has a field called "Other time:". It is an input box. When the interface is Hebrew, the default value of that box is still in English: "infinite".
I asked at translatewiki.net whether it can be localized. Raymond said that it's complicated and requires a more thorough solution (link: http://translatewiki.net/wiki/Thread:Support/unlocalized_default_value_for_a_field_in_Special:Stabilization )
(NB: This report refers to the version of FlaggedRevs which is currently installed in the Hebrew Wikisource. I think that it is a vanilla installation that reflects the defaults, at least as far as this page is concerned, but it may have some modifications.)
Version: unspecified
