I think I just broke R

I swear, I didn't touch it!
I can't fit GLM's anymore, and I can't make it talk english (for 
googling the error messages) anymore.

y <- c(1,1,0,1,0,1)
x <- c(2,7,3,5,2,4)
glm(y~x, binomial)

Fehler in runif(length(pi)) :
   Element 1 ist leer;
   Der Teil der Argumentliste 'length' der berechnet wurde war:
   (pi)

Sys.setenv(LANG="EN")
glm(y~x, binomial)

Fehler in runif(length(pi)) :
   Element 1 ist leer;
   Der Teil der Argumentliste 'length' der berechnet wurde war:
   (pi)


I may suffer from sleep deprivation and minor confusion... maybe. But 
this is just weird and I can't explain it.

I run R from Emacs/ESS, if that matters.

Any help would be appreciated!
