[GiNaC-list] Not factoring expression

I've just started using GiNaC (and very nice it is too!), however I
have some strange behavior with an expression not being simplified.
One output of a linear equation solver is the expression:
What is happening is that the V_1 terms in the first bracket are not
being factorised, and therefore no cancellation with the final
(V_1)^(-1) term is occuring. All my symbols are created with a
SymbolFactory pattern, so I can be sure each V_1 is the same object.
Can anyone suggest why GiNaC isn't simplifying this to cancel the V_1
