Just reproduced this with network-manager version "0.7~~svn20080818t061112+eni0-0ubuntu1" on x86-64, Intrepid.
Steps were: - plug in modern Sony Ericsson phone - reboot phone while USB connected, putting it in a particular mode -> we see two cdc_acm interfaces visible, followed by networkmanager crash: $ dmesg [snip] usb 6-1: new full speed USB device using uhci_hcd and address 4 usb 6-1: configuration #3 chosen from 1 choice cdc_acm 6-1:3.1: ttyACM0: USB ACM device cdc_acm 6-1:3.3: ttyACM1: USB ACM device usb0: register 'cdc_ether' at usb-0000:00:1d.0-1, CDC Ethernet Device, 01:08:0a:35:03:00 nm-system-setti[6493] trap int3 ip:7f5e6ced5c54 sp:7fff77cc9d80 error:0 -- [apport] NetworkManager crashed with signal 5 in main() https://bugs.launchpad.net/bugs/85113 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
