[R] NA handling problem in capscale (vegan)

I am having a problem with NA handling in capscale function.

as I understand it from the help capscale should permit NA values when 
na.action=na.mit or na.exclude,

however I am getting  the error

Error in X[nas, , drop = FALSE] : incorrect number of dimensions

trivial example is pasted below.

library(vegan)
mydist<- matrix(1:25, 5, 5)
mydata<-matrix(rnorm(1:25),5,5)
mydata[3,1]<-NA
mydata<-data.frame(mydata)

capscale(mydist~X1+X2+Condition(X3),data=mydata,na.action = na.omit)


Thanks
