Public bug reported: Occasionally when I am manually switching from one WiFi network to another through the Indicator applet, the entire system freezes completely—neither the laptop's own keyboard and trackpad nor any USB devices produce any effect. The only way to resolve the situation is then to force a power down, which has caused me to lose data on several occasions.
This started occurring on Xubuntu 15.04; I have not had any similar bugs on previous iterations of Xubuntu or other Ubuntu variants. It seems to happen when I am switching from an unsecured to a particular WPA-secured WiFi network, though as it happens only once in a while (about once every two days or so under moderate computer use) I am not sure about the source of the issue. I do know that it seems to happen only while switching WiFi networks. This is one of two new network-manager bugs that I noticed around the same time, immediately after upgrading to 15.04.
