segmentation fault crash

I'm running 2.02 f51dc11 on a Dell XPS 13 running Ubuntu 14.04 and I get near random, but constant crashes. Sometimes right on startup, sometimes after a few minutes of work. There does not seem to be a discernible pattern. This renders Musescore useless. I've also tried installing the nightly, but I get the same result. I know that some have had success preventing the start up crash by disabling the start center, I have done that but still encounter problems. When I run from the terminal this is what it shows:

greg@hummingbird:~$ mscore
initScoreFonts 0x31dec00
init Help from:

Any help would be appreciated. I only have Ubuntu on my machine and would really like to be able to write out exercises for my students.

Thanks,
Greg
