SomeoneElse
The name:ru of the former Berlin Wall http://www.openstreetmap.org/relation/6651797 is currently set to "Берлинская_стена".  It seems odd that it has an underscore in it.  I asked about it a while back on http://www.openstreetmap.org/changeset/43634303 and the author of that changeset doesn't know, so maybe someone more local does?
Best Regards,
Andy
