read.table

Dear R community,   I encounter a problem reading data into a dataframe. See
attachment for the input. I use:
data<-read.table("test",fill=T,row.names=1)

When you look at "data" you can see that some lines of my input were
broken... I can avoid this problem by sorting the lines by length... Do I
have it wrong or is there a bug?

Thanks and wishing you a great remainder of the day,
Georg.
