Binomial Models

I am using a family model to look at the variance components of a binary 
trait (single or multi-stemmed) in forest trees.  Using the !bin qualifier 
I get the variance components, but their standard errors bear no 
relationship to their significance as judged with the LRT - SE's of <1 can 
have a LL diference of >100!.

Presumably I can use the variance components directly in heritability 

Is their any way of running a bivariate binomial model?  Using the !bin 
qualifier in a bivariate model causes ASREML to crash.
