Bug Description
Binary package hint: plasma-
Crash looks similar to bug #408508, but that is reported as "fix released" on August 18th, and I just did a complete safe-upgrade of my Karmic system. Also, it happened while doing a restart of network-manager.
Opening a new bug so I can look at my stack trace again to compare to the bug #408508 stack trace.

deviceUni is the only function that is the same between the two stacktraces. These are two separate crashes.

Actually I was manually restarting network manager as it had failed to pick up my IPv6 router advertisement and thus didn't assign a global IPv6 address. So the crash actually happened during "normal operation" rather than during an upgrade.

From bug 222257:
---
Some more information: The crash happened on my laptop using wifi and a wpa
secured network. If I disable wireless connections or use a wired connection
instead, then knetworkmanager does not crash. As soon as I enable wireless and
restart network-manager the crash appears.

This problem is caused by dangling pointers left in ActivableLists before NM starts again. Last November I commited a patch to workaround this problem by emptying the ActivatableList when NetworkManager goes down. It fixed the problem in my tests. Please upgrade to a recent networkmanagement (Plasma NM) revision.

Prevents a crazy flux of several networkDisappeared signals for the same ssid

result is the same as using wirelessEnabled

This is odd. If you restarted kdm all kde session should have been restarted as well, including kded. It is very unlikely this bug happens on an fresh starting kded. NetworkManager is not supposed to restart because any of its clients (Plasma NM, nm-appplet, whatever) have restarted. Are you sure what you restarted was kdm? You said kdm frozen, I have never seem kdm freezing. What were you doing before the freezing?

Can someone reproduce this problem with a recent Plasma NM snapshot? Please keep in mind still today some distributions ship a very old version of Plasma NM from last year. When testing please use a recent version, in the past three months we fixed tens of bugs in Plasma NM, so you must test with a recent version.

I think the issue is long gone, I haven't noticed it for maybe 6 months or a year. I have just verified in KDE 4.6.3 and found no problems.

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. It would help us a lot if you could test it on a currently supported Ubuntu version. When you test it and it is still an issue, kindly upload the updated logs by running apport-collect 453697 and any other logs that are relevant for this particular issue.

Hm, the stack trace looks very similar to bug 408508. Are we sure that bug is fixed?
