Draftsight Freezes on startup Xubuntu

I have installed Draftsight on Xubuntu 12.04 and install went ok but as soon as i try to start Draftsight it freezes, at first I thought it was the performance feedback dialogue box but seems i have managed to get past that box and now it still freezes.

I have un-installed and removed all the config files i could find then restarted and still no luck.

I have also tried V1R3-1 and V1R3-2 and still no luck.

any ideas would be great, I have never had this problem before on any of the other systems i have run it on, Ubuntu and winblows
