Bug Description
Running Ubuntu Karmic. an update to either HAL, NetworkManager, or nm-applet in the last 48 hours has caused network manager to flail when a 3G mobile broadband USB device is inserted.
The behaviour is very strange. Sometimes it works when first plugged in after a fresh boot, but subsequently inserting the device the nm-applet "connecting" indicator spins at something approaching lightspeed, and the CPU is pegged 100%.
The NetworkManager process shows up as the thing eating the processor; tried killing it, but it's respawned replacement shortly resumes 100% CPU consumption and mad spinning.
I've had one success by killing the demon AND the applet then restarting [the latter], but in the main I've had to reboot to fix it; I had to find an open wifi access point to report this. The whole stack was running fine until Saturday.

It is possible that this is related to the "Available to all users" checkbox in the Edit Connections... -> Mobile Broadband -> Edit $connection dialog.
When that was first checked, I had to escallate to root priviledges, (presumably so the NetworkManager demon could be instructed); susequent attempts to edit the connection resulted in an error dialog, something to do with authentication or permissions lacking. Anyway, at that point, trying to delete the connection, start over, etc, reconnecting the device pegged the CPU at 100%.
