"Unread content" number changing

[Kjell Iver Johansen]

I updated yesterday to 4.5.3 and all went smooth. 

I notice that in my language the New Content number of days (that are 365 days in English) -

gets a random number i Norwegian.  The number fluctates from 0 til many many millions of days.

anyone has a suggestion to this one? Could not find or see the bug-tracker..

In key "stream_blurb_relative" change %d to %s.
