This appears to be logged by wsdd (which gvfsd runs as a subprocess if
available) rather than by gvfsd itself: reassigning.
Probably this indicates that some device on your network has an invalid
UUID, or a UUID in a format that wsdd wasn't expecting, and wsdd should
perhaps be more robust against that.
