Title:
Network manager crashes and restarts 2 seconds after establishing a
VPN connection
Status in network-manager package in Ubuntu:
Fix Released
Bug description:
When trying to get on a company VPN, the connection is initially
established and works (I can access intranet websites), but after ~1-2
seconds from starting VPN connection the Network Manager seems to
crash and restart, taking all connections down. This makes VPN totally
unusable.

Can you at least tell me if there is a workaround for this?
