Fixing this bug reveals another one. We do a:
value_new = xstrdup(val);
value_new = strim(value_new);
When 'val' has whitespaces at the beginning we no longer free the
pointer originally returned from xstrdup, but the pointer with
whitespaces stripped. I'll queue a fix for this before this patch.
Good catch.
ACK
