Follow-up bug

[GoogleCodeExporter]

no seen so far but I know there is a bug I must correct. 

The previous jobs no longer exists, and the same goes for their informations. 
Thus, I can't know the duration time of the simulation. 

I don't know if it exists a way to access thoses informations, but in my code, 
for simulation that are finished or simulation that were continued, I try to 
get infos for deleted jobs, and I will get errors.
