Don't override admin changelist actions "Go" button translation with one for the search form "Go" button (by giving the second one some context).
Search form "Go" needs to be translated to something like "Search and change page", but the one in admin has a different meaning -- "Execute the action".
Note: template contexts require Django >= 1.4, with a bit more work this could also be solved using `pgettext` introduced in 1.3.
