Please use chimera's Report a Bug dialog to submit this bug.  It will tell 
me more about your system and what graphics driver you have installed so I 
will have a better chance of reproducing the bug.

That said, I see that the backtrace says that /usr/lib/nvidia/libGL.so.1 
was involved.  That file is not part of the NVidia driver from 
www.nvidia.com, so I'm guessing you must have the open source version.  If 
you switch to NVidia's version, then it should work.  But before you 
switch, please submit the bug report so I'll know which driver is buggy.

If you are stuck with the current graphics driver, you can workaround the 
bug by starting chimera with the --debug-opengl option and disabling 

 	Thank you and good luck,
