I just got this too. I was already running a 3G Huawei modem in another USB port that was happily connected to the 3G network. I plugged in my Sony Ericsson c902 (to charge it) and, like Foaming Draught above, the nm-applet disappeared and Apport did its thing.
I've previously told the Network Manager not to dial this modem (the one in my phone) but it does it anyway - perhaps a separate bug? It seems that restarting NetworkManager leaves it in a confused state - the icon says it's disconnected, even though the original Huawei connection is still running. -- NetworkManager crashed with SIGSEGV when I connect a 3G mobile phone https://bugs.launchpad.net/bugs/278468 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
