summary() error for mxRowObjective

summary() called on a model with an mxRowObjective dies with the message:

> summary(rmodRun)
Error in inherits(x, "factor") :
no slot of name "dims" for this object of class "MxRowObjective"

This is not a 1.0 priority, but is likely an easy fix if someone is looking at summary() anyway.

This works in the 2.0 Beta and was likely fixed a long time ago, in a galaxy far, far away....
