Description Oscar 2013-02-19 15:02:13 CET 
Physics for simulating generic ion is not loaded. 

When running a simulation using a generic ion with the following command:

/gun/particle ion
/gun/ion 6 12 6
/gun/energy 10 MeV
/run/beamOn

I get this print out:

### Run 0 start.

A quick-fix I used was to use the PhysicsList from N03 (with the appropriate changes) and then the example ran well. 

Cheers!

Hello,

The observation and the fix are correct. The fix will be included in the next geant4 patch.
