I tried out the vpn applet, and it's quite buggy - you can't delete old configs, the new/edit/import window import and cancel buttons don't work reliably, and if there's an path to a file it doesn't like (even if valid) it complains.

Anyway, I finally managed to create a config file it didn't hate, putting the config, keys and crts in MyDocs/openvpn, and did the import. I got it to attempt to connect and it failed, and the whole hildon GUI locked up.

Rebooted and the vpn applet won't start at all. I guess I need to wipe its config and start again. Hopefully with a clean start it'd work. I know the config does work as I've done it from the command line OK.
