Hi I experience the same problem on one of my 64bit oneirc systems. I just upgraded two machines from natty to oneirc, and one of them is affected by the bug, the other not. Very strange.
Anyway I followed the instructions mentioned in post #2 and attached the resulting file. Bye, Franco Further info: uname -a Linux TM6292 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux cat /proc/version Linux version 3.0.0-12-generic (buildd@crested) (gcc version 4.6.1 (Ubuntu/Linaro 4.6.1-9ubuntu3) ) #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC 2011 ** Attachment added: "gdb-gnome-control-center.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/854802/+attachment/2545372/+files/gdb-gnome-control-center.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/854802 Title: User account manager does not start (closes immediately) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/854802/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
