*** This bug is a security vulnerability ***
Public security bug reported:
To replicate:
1: Connect to a Wi-Fi network with 75% signal strength or less
Expected results:
Network Manager should remain connected as much as possible, and automatically
reconnect when necessary.
Actual results:
The Wi-Fi password confirmation dialog is repeatedly shown even when the Wi-Fi
password has not changed. The memory-consumption of nm-applet increases each
time, often up to 200MB over the course of 8 hours.
