Segmentation fault with DS Visualizer on ubuntu 12.04

Dear All,

I installed DS Visualiser 3.5 on a ASUS Zenbook on 64 bit Ubuntu 12.04. Whenever I open molecule and put some labels on it, the program crashes with the message:

Segmentation fault (core dumped)

I tried the old 3.0 version too, same result. The message is not very informative, so I have no idea what I could do. I would appreciate any help.

Thanks in advance!
