Mediation/indirect effects is  a surprisingly complicated problem in
non-linear models like -logit-. Various solutions have been proposed,
and there is no consensus yet on which one is to be preferred for
which situation. See for example:

M. Sinning, M. Hahn, and T.K. Bauer (2008) "The Blinder-Oaxaca
decomposition for nonlinear regression models." The Stata Journal,
8(4): 480--492.

M.L. Buis (2010) "Direct and indirect effects in a logit model", The
Stata Journal, 10(1), pp. 11-29.

Karlson, K.B. and A. Holm (forthcomming): "Decomposing primary and
secondary effects: A new decomposition method". Research in
Stratification and Social Mobility.

All of these have implementations in Stata, type in Stata
respectively: -findit nldecompose-, -findit ldecomp-, and -findit
khb-.

Hope this helps,
Maarten
