Crash when copying atoms on Ubuntu 12.04

[cryos]

To reproduce, draw a molecule (just click with the draw tool to draw methane).

Change to the select tool, select an atom, then go to the menu: Edit->Copy

Crash, with backtrace below.

This with a fresh build on Ubuntu with avogadro-squared, and the distribution Qt:

Application version: 1.1.0 Git revision d9e5d4f
OpenBabel: 2.3.90
Qt: 4.8.1

This problem isn't Ubuntu-specific. I got the same behaviour with Windows 7.
