I built without yajl support, and noticed a strange failure message in qemumonitorjsontest: 2013-02-22 16:12:37.503+0000: 19812: error : virJSONValueToString:1119 : internal error No JSON parser implementation is available 2013-02-22 16:12:37.503+0000: 19812: error : qemuMonitorJSONCommandWithFd:253 : out of memory While a later patch will fix the test to skip when json is not present, this patch avoids overriding the more useful error message from virJSONValueToString returning NULL. * src/qemu/qemu_monitor_json.c (qemuMonitorJSONCommandWithFd): Don't override message. (qemuMonitorJSONCheckError): Don't print NULL. * src/qemu/qemu_agent.c (qemuAgentCommand): Don't override message. (qemuAgentCheckError): Don't print NULL. (qemuAgentArbitraryCommand): Properly fail on OOM.
