bug in glm (PR#397)

[holzer@stat.math.ethz.ch]

Dear R-team

As I didn't get any answer to my bug-report last week I have taken the
effort and extracted a minimal data set from my data (see below) where the
following bug occurs:

> glm(SKR.ein.aus ~ ., family = binomial, data = bugdata, na.action = na.omit)
Error in names<-.default(*tmp*, value = ynames) : names attribute must be the same length as the vector
In addition: Warning messages: 
1: fitted probabilities of 0 or 1 occurred in: (if (is.empty.model(mt)) glm.fit.null else glm.fit)(x = X, y = Y,  
2: fitted probabilities of 0 or 1 occurred in: (if (is.empty.model(mt)) glm.fit.null else glm.fit)(x = X, y = Y,  
3: fitted probabilities of 0 or 1 occurred in: (if (is.empty.model(mt)) glm.fit.null else glm.fit)(x = X, y = Y,  
4: fitted probabilities of 0 or 1 occurred in: (if (is.empty.model(mt)) glm.fit.null else glm.fit)(x = X, y = Y,  
5: fitted probabilities of 0 or 1 occurred in: (if (is.empty.model(mt)) glm.fit.null else glm.fit)(x = X, y = Y,  
6: fitted probabilities of 0 or 1 occurred in: (if (is.empty.model(mt)) glm.fit.null else glm.fit)(x = X, y = Y,  
7: Algorithm did not converge in: (if (is.empty.model(mt)) glm.fit.null else glm.fit)(x = X, y = Y,

I hope, this makes it possible to find the bug.
