This bug affected my system while connected to a Wireless network. The crash occured after approximately 2 hours of being on the network.

Crash occurred while I was updating Intrepid today even though i didn't see any network-manager related updates. Was connected to Wifi WPA2 at the time.

[Johan Ryberg (jryberg)]

Got the same crash while updating Intrepid today. NetworkManager just disapered and a crash report was generated

[Pedro Villavicencio (pedro)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Thanks in advance.

[ThomasMartitz (thomas47-deactivatedaccount)]

I'm having this problem using karmic alpha 6.

[Octi (octavianiolu)]

Same as #11

[Octi (octavianiolu)]

And today again...

[amano (jyaku)]

Still an issue. I am here on a wired connection. A few seconds after the desktop fully loads the crash occurs. And as I see there are already 5 duplicate bugs thus we can conclude that this IS a common issue...

[amano (jyaku)]

The bug was marked incomplete. What information is missing to justify this status? Setting it to confirmed for now...

[Tony Espy (awe)]

It was marked Incomplete because there weren't any updates to the bug in over 9 months during which many, many updates of network-manager have been released. As this was reported against an old release, we wanted to see if this was still an issue with Karmic.

amano, if you're getting the *same* crash as aaronjlynch with Karmic Beta + the latest updates, then by please run the following command:

apport-collect 274760

...to add information to the bug that'll help us figure out what's going on.

If you're getting a *different* crash, then please report a new bug using the command:

ubuntu-bug network-manager

Moving back to Incomplete until the requested information is supplied...

[Frederick F. Kautz IV (fkautz)]

Does karmic contain a debugging version of either network manager or glib?
This error seems to occur more often during alpha/betas. At full release on
9.04 the problem appeared to go away on my system.

I cannot decide, whether this is the same bug, or just a new similar one. This is what the SegvAnalysis from the bug reporter told:

Segfault happened at: 0x333051 <g_object_unref+33>: cmpl $0x50,(%eax)
PC(0x0033351) ok
source "$0x50" ok
destination "(%eax)" (0x0000002c) not loaded in a known VMA region (needed writable region)!

bug reporter = crash reporting tool

[amano (jyaku)]

One of the recent karmic updates fixed this issue for me. Tnx to the ones responsible for the fix.
