I can't identify the problem. The package author and maintainer,
Paul Gilbert, might be able to help.
Have you tried "debug(SS)"? This will allow you to walk through
the function line by line looking at things, etc. This often produces
enlightenment.
Alternatively, have you considered the "dlm" package? In addition
to a vignette, it has a companion book, Petris, Petrone, and Campagnoli
(2009) Dynamic Linear Models with R (Springer).
Hope this helps.

I tried to specify a model in dse1 but something isn't right. Anybody
have any tips?
model<-SS(F=f,G=g,H=h,Q=q,z0=z,P0=p)
Error in locateSS(model$R, constants$R, "R", p, p, plist) :
The dimension of something in the SS model structure is bad.
dim(f)

dim(z)
