[R] confint fails in quasibinomial glm: dims do not match

[smith_cc]

I am unable to calculate confidence intervals for the slope estimate in a
quasibinomial glm using confint(). Below is the output and the package info
for MASS. Thanks in advance!

R 2.9.2
MASS 7.2-48

> confint(glm.palive.0.str)
Waiting for profiling to be done...
Error: dims [product 37] do not match the length of object [74]
> glm.palive.0.str

Call:  glm(formula = cbind(alive, red) ~ str, family = quasibinomial,     
data = subset(master.palive, vtime == 0)) 

Coefficients:
(Intercept)         strs  
       1.05         1.01  

Degrees of Freedom: 36 Total (i.e. Null);  35 Residual
Null Deviance:	    20800 
Residual Deviance: 16200 	AIC: NA
