I'll have to fix dependencies together with this SRU. Please hold while I fix this new debdiff (for this case), fixing lib dependencies for pacemaker to be upgraded.

I've checked upstream code and there might be 2 important commits that could be cherry-picked to fix this behavior: commit f2a637cc553cb7aec59bdcf05c5e1d077173419f Author: Andrew Beekhof <[email protected]> Date: Fri Sep 20 12:20:36 2013 +1000 Fix: services: Prevent use-of-NULL when executing service actions commit 11473a5a8c88eb17d5e8d6cd1d99dc497e817aac Author: Gao,Yan <[email protected]> Date: Sun Sep 29 12:40:18 2013 +0800 Fix: services: Fix the executing of synchronous actions The core can be caused by things such as this missing code: if (op == NULL) { crm_trace("No operation to execute"); return FALSE; on the beginning of "services_action_sync(svc_action_t * op)" function. And improved by commit #11473a5.
