To reply, in case anyone reads this, the problem was of course in the setup
of the matrix, and there are two possible solutions.
The first, for a model with only a single set of groupings, is to use mcp.
So, even with this contrast matrix
contra-rbind(A v. B = c(-1,1,0,0),

distribution with a log link seemed like the logical choice, and so
I've modeled it as such.
