One of today's leak-plugging patches introduced a bug. Fortunately, it can strike only when libvirtd is about to fail anyway. The consequence is that instead of failing in an orderly manner, it would probably segfault. Sorry about that. Here's the fix: Avoid segfault upon early libvirtd failure. * qemud/qemud.c (main): Don't call qemudCleanup on an uninitialized pointer. By the way, even though this evoked a warning from gcc, "make distcheck" passes. Obviously, that means the distcheck rule is inadequate. I'll fix it so that it turns on -Werror for the final build.
