In a terminal, kill the running NetworkManager, and run a new one within gdb: $ sudo killall NetworkManager $ sudo gdb NetworkManager (gdb) run
Now, connect to vpn and you should get the gdb prompt again when NetworkManager crashes. (gdb) gcore Saved corefile core.16883 (The number will most likely differ for you) Attach the core file to this bug. That should be really helpful.
