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 Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1157780 Title: "stop networking" crashes window manager To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1157780/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
