[R-sig-ME] interpreting Std. error from glmer output

I want to plot my predictions from a model and use the standard error
output as a measure of dispersion as I am unable to calculate confidence
intervals with mcmcsamp as I have a binomial distribution.
I know that the estimates are deviations from the intercept.
Fixed effects below:
Estimate Std. Error z value Pr(>|z|)
(Intercept) 2.90836 0.34041 8.544 < 2e-16 ***
treatment2 -0.73507 0.12986 -5.660 1.51e-08 ***
treatment3 -1.20052 0.12371 -9.705 < 2e-16 ***
So the estimate for treatment 2 is 2.9 + -0.73. Are standard errors also
deviations from the intercept? i.e. 0.34 + 0.13 for treatment 2?
