Usually odd crashes are caused by a faulty graphics driver.  So if you 
have an AMD/ATI or NVIDIA graphics card, you should install the 
proprietary drivers,  they are more robust than the open-source ones and 
faster too.  If you have Intel graphics, then you might be out of luck 
depending on which model you have, but in general, you want the newest 
version of the driver you can get which means the more recent desktop 
Linux you can get -- the Intel driver is under very active development 
right now.

If you use chimera's Help / Report a Bug dialog to report this as a bug, 
that will tell me about the hardware in your system and which version of 
Ubuntu you have and then I'll be able to help you better.
