Thanks Charles.

The error is occuring in a fit of a glm using the fixed-effects terms only. This fit provides the starting estimates for the fixed effects in the GLMM model. I changed the way that this fit is performed and apparently didn't do it correctly.

I think it would be better if you and I corresponded off-list about this.
