after last upgrade of network manager in Karmic - my nm-appler work ok only one time - after upgrade. Then, start until now, at each boot I got "Network Manager is not running" and when I wanna edit connections no connection are shown for my DSL

[Jean.c.h (slug71)]

Affected by this too. Did a fresh install of Karmic 64b Alpha 4 and all updates applied.

[Nemes Ioan Sorin (nemes-sorin)]

seems to be related to pilicykit / consolekit - something gows wrong
with rights doe the new changes in Karmic - I hope they will solve
that around launch date

- seems like the new technologies regarding rights administration is
still a hard stone for Linux.

[I filed a duplicate bug 411778] On my system NetworkManager crashes in the described way I have the Miredo Teredo tunnel setup. If I turn it off, there is no crash.

[Kẏra (thekyriarchy)]

Latest update fixes this for me, but now i get this: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/150665

[Tony Espy (awe)]

Can the original bug reporter please confirm whether or not this crash is resolved for them with the latest update? If so, we can change the status to FixCommitted.

[Ryan (ubuntu-draziw)]

I think I just had the same type of crash (same g_type_check_instance_cast - submitted in case the trace doesn't match.
