nm-openvpn-service crashed with SIGSEGV in strlen()

Binary package hint: network-manager-openvpn

Using networkmanager on an up-to-date (Kubuntu) Jaunty installation on an AMD64 laptop, connected to the net via wlan.

When I tried to open an OpenVPN connection via the NetworkManager plasmoid of Kubuntu, this crash occured.

Excerpt from /var/log/daemon.log:

I want to add, that I didn't enter any password data into the NetWorkManager Plasmoid dialog, but expected to be asked for the password at a later stage. Maybe this was the cause for the crash?

[Olaf Lenz (olenz)]

I just want to confirm: The bug still happens in a newly installed karmic RC.

[Justin Huff (jjhuff)]

Olaf,

Looks like the missing password is the key. I added the PW and I'm now crash free!

[Olaf Lenz (olenz)]

Ok, nice catch.
Not a very nice bug, though - I don't like to store my PW on the disk...
