I frequently get this as well, but never while wandering. It\'s always the first thing that occurs (and the last!) when I enter the game. It happens about half the time I run it. Here\'s what it looks like on the console:
planeshift.application.client:
PSLoader: step 5: success

:
Failed to set trait mesh=\"0\" mat=\"0\" tex=\"0\" shader=\"0.6,0.6,0.6\"/> for mesh.
