>Summary: Segfault when opening CH4 if "cartoon" engine is active

Initial Comment:
I get a segfault when opening testfiles/methane.FChk, using RC1 of avogadro-1.1

OpenBabel converts this fine, and avogadro-1.0.3 as well.

Message:
Seems to only happen when I open methane, even the .xyz file of it. Maybe a
symmetry thing?

This is the backtrace I get:

Message:
OK, I found it: it only happens when the "cartoon" engine is activated.
