I only get these messages with a dbus-enabled, optimized (-O3) build on Mac OS X 10.5.8 (i386) - IIRC the dbus-enabled build also sometimes produces other (critical) console warnings when working with multiple windows (within one Inkscape instance), after closing a window.
A normally configured build (without dbus, compiled with '-O0') doesn't produce the warnings.
