Tvheadend

Hi - this may noty be a TVH issue, but maybe someone has some ideas...

I'm running Mint 16
I have tvheadend 3.5 installed from the repositories
I can view TV by running (from the command line)

vlc http://192.168.1.1:9981/stream/channelid/50

From chrome however, the VLC plugin crashes, with the following errorsa output on the terminal:
