Still not enough.
 From your first post, the error was:

> 'NoneType' object has no attribute 'exec_command'

>     def command ( self , command ) :

So you'll have to analyze how (and when) self._ssh might become None. This  
function just *uses* self._ssh - look for some other places where  
self._ssh is assigned to (or perhaps, deleted, if there is a class  
attributes set to None).
