use %d instead of %s for vars that are numbers and ngettext()
python doesn't choke on '%s' %0.4 but then we cannot easily control what is string and what is number
we wanna know what is number because
a. at the time of the coding writing %d means we should ngettext()
b. at the time of reviewing for strings freeze it's easier to see places where we missed doing that
one place is #: ../src/dialogs.py:692 #, python-format msgid "Gajim - %s unread messages" msgstr "Gajim - %s nepřečtených zpráv"
