Would you clarify what you do to stop networking? Such as in the GUI or using ifconfig.
On 15.10 Beta 2, I've tried unticking "Enable Networking" from the panel icon's menu and, although the window manager doesn't crash, there is a system software problem error message. Upon the next login, Apport reports the attached error. ** Attachment added: "_sbin_wpa_supplicant.0.crash" https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1157780/+attachment/4484835/+files/_sbin_wpa_supplicant.0.crash -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity in Ubuntu. https://bugs.launchpad.net/bugs/1157780 Title: "stop networking" crashes window manager Status in Unity: Confirmed Status in unity package in Ubuntu: Confirmed Bug description: When running e.g. "stop networking" from within Unity, it succeeds, but the window manager then crashes, leaving undecorated windows.
