Hello All,

I'm pretty sure I found a bug in the main galaxy distribution. The following code diff shows the introduction of the line

tool_version = self.__get_tool_version( trans, tool_id )
but if you look at the function definition containing that line, you see

def from_workflow_step( Class, trans, step ):
which does not half a self in it. Then we get an error.
