commit 139d367f297575a59b96b64a633ed2b6988d60e1 Author: Nick Mathewson nickm@torproject.org Date: Sun May 5 18:52:53 2013 -0400

Fix 8833: crash bug from using NULL node->ri in dirserv.c

It appears that moria1 crashed because of one instance of this (the one in router_counts_toward_thresholds). The other instance I fixed won't actually have broken anything, but I think it's more clear this way.
