Redmine

On windows 7 redmine(1.1.3.stable) falls when loads mercurial repo containing files with cyrrillic names.
Error message: PGError: ERROR: invalid byte sequence for encoding "UTF8"...
Error placed at app\models\changeset.rb row 175.
For me this code works:

# Creates a new Change from it's common parameters
def create_change(change)
Change.create(:changeset => self,
:action => change[:action],
:path => Iconv.conv('UTF-8', 'WINDOWS-1251', change[:path]),
#:path => change[:path],
:from_path => change[:from_path],
:from_revision => change[:from_revision])
end

Of course it isn't true way. But I don't have Ruby knowledge for correct fix.
