The fact that the slave sees the last_value as ahead of the master is
not a bug; you'd have the same last_value on the master if it were to
crash and restart. (This is due to a tradeoff made long ago to reduce
the amount of WAL traffic created by nextval: only one WAL record is
written per 32 nextval's, and that record claims last_value is 32 ahead
of what it previously was.)
There is a known bug, fixed in 9.1.5, associated with sequences that
have been ALTER'd ... but that's not what you're showing here.
