Can't import new sample "segmentation fault"

Hello, I'm a new user of linux and hydrogen. I'm on Ubuntu. And I have used hydrogen for 3-4 month but for some time, when I want to change my samples, hydrogen is closed immediately. And I don't know what I should do. If somebody have an idea that would be really cool. I puts to you what he says to me in the terminal:

robin@robin-linux:~$ hydrogen
