Thanks. This is a bug, the source code made an implicit assumption that there would always be at least one smooth, when creating the gam object after fitting. Fixed for the next release (1.7-5). For now, you could use glmmPQL from the MASS library to get an equivalent fit when there are no smooth terms.
