  We show that in a broken supergravity theory any field that acquires a vacuum
expectation value obtains at the same time a non vanishing F-term whose natural
size is given by $<\theta> m_{3/2}$. These F-terms contribute unsuppressed to
the trilinear couplings and have observable effects in the low energy
phenomenology. We show that \mu --> e \gamma decays can receive large
contributions from this source at the level of current experimental bounds.
Therefore this decay may provide the first clue of the structure of the soft
breaking sector with the proposed experiments in the near future.
