NetworkManager[4888]: segfault on wireless up in intrepid

[Marc MERLIN]

I start networkmanager
I rmmod, insmod my iwl3945 driver and connect to a WPA network with a script I already had.

Quite frankly, networkmanager has become a real pain in the ass for me in intrepid. In hardy it would at least let me manage things by hand, and it would follow along, giving me an ifdown when I unplugged an ethernet cable on my eth interface that I managed myself.
Now, in unmanaged mode it does nothing, to the point that I'm going to have to remove it and re-install ifplugd unless you tell me otherwise, and if I try to let it manage interfaces that I do need to handle by hand sometimes, including wireless, it either kills the connection I just brought up, or it segvs.
Maybe it works for some, but boy is it a real pain for the rest of us :(

Thank you for taking the time to report this bug and helping to make Ubuntu better. However, your crash report is either missing or challenging to deal with as a ".crash" file. Please follow these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer.

If you are running the Ubuntu Stable Release you might need to enable apport in /etc/default/apport and restart.

If you are using Ubuntu with the Gnome desktop environment - launch nautilus and navigate to your /var/crash directory and double click on the crash report you wish to submit.

If you are using Kubuntu or Xubuntu you can file the crash using /usr/share/apport/apport-qt --crash-file=/var/crash/_my_crash_report.crash in a terminal - where _my_crash_report.crash is the crash you would like to report.

I'm closing this bug report since the process outlined above will automatically open a new bug report which can then dealt with more efficiently. Thanks in advance for your cooperation and understanding.
