I am getting an error, that I have no idea what to do about, from glmmTMB():

fmla <- cbind(Dead, Alive) ~ (Trt + 0)/Dose + (Dose | Rep)
X    <- dget("X.txt")
fit  <- glmmTMB(fmla, data = X, family = betabinomial(link = "cloglog"),
                dispformula = ~1)

> Error in optimHess(par.fixed, obj$fn, obj$gr) : 
>   gradient in optim evaluated to length 1 not 16
> In addition: There were 16 warnings (use warnings() to see them)

The warnings are all repetitions of

> 1: In nlminb(start = par, objective = fn, gradient = gr,  ... :
>   NA/NaN function evaluation

The error sounds to me like something is amiss in the code.

Can anyone confirm/deny/suggest what I might do to get this call to 
glmmTMB() to run?
