Comment 17 for bug 824255

Still happens here. I'm using the dispatcher script from http://wiki.ubuntuusers.de/NetworkManager/Dispatcher, at the bottom (when I connect to a specific WLAN network, I automatically want to establish a VPN connection). Here's waht happens when I connect to the WLAN network specified in the dispatcher script:
