This I can repeat fairly consistently. For me, it's much more likely if do something unexpected to the tool, e.g. close it while the measuring string is active.

The GPS Information tool (live tracking) used to leave it's position marker behind when you closed it in 1.7, but doesn't seem to do in 1.8 so maybe that provides some hints?
