Comment 32 for bug 1480877

Hotspot management code that subscribes to NM events [1] was recently moved from System Settings into indicator-network. The code is quite comprehensive whenever you have previously created a hotspot. Those affected by the bug should 1) see if they have previously created a hotspot and 2) see if by removing the hotspot, the issue is resolved (sudo rm /etc/NetworkManager/system-connections/<hotspot name> && sudo reboot).

This wasn't an issue when the code was bound to System Setting's life cycle, but it may be an issue for the indicator.
