I couldn't reproduce the problem; it appears to depend upon whether the file-scope variable 'otmp' has a stale value, and that might happen after a monster has tried to steal mon's saddle. However, the code pointed out in the report is clearly wrong. This prevents feedback of "glorkum" (with plural verb since quantity of 0 isn't 1), but the potential stale value hasn't been dealt with.
