Solve problem ?

Please, could someone explain the discrepancy between these two results :

Solve[ { u + m/x^2 v, v + m/x^2 u } == 0, {y,z} ]    =>    {}

Solve[ { u + 1/x^2 v, v + m/x^2 u } == 0, {y,z} ]    =>   {{}}

The math meaning is not significant (these are simplified from the actual case),but in a larger program I do Length[ result[[1]] ], and it objects to the first
instance (which I think is incorrect).

Thanks.
