Sometimes, steamwebhelper falls over repeatedly (every 3 minutes) with text such as the following being logged to …/Steam/logs/webhelper-linux.txt:

Various games hang on start-up when this happens.

The problem appears to occur randomly, but has so far been noticeable a few minutes after starting Steam (which leads me to wonder if the trigger is a race condition during startup); restarting Steam has so far been enough to restore normal behaviour.
