Public bug reported:
Binary package hint: network-manager
After suspending and resuming my laptop several times, network manager
crashes. The icon retains whatever state it had when I last suspended
the machine, but it will not find new networks, and it does not connect
even though the icon shows it as connected to whatever was there before
the suspend. I think it happens after 4-5 suspend/resume events
(without reboot inbetween). This is a fresh gutsy install (not
upgrade).
In the syslog, I found these errors:
