This "bug" is demonstrated in the following StackOverflow post:
When you plot a data column, but there is no useable data in the the column, gnuplot still reserves space in the key even though it doesn't put a "title" in the key. This behavior changed at some point between gnuplot 4.4.2 and gnuplot 4.6.0 (tested on OS-X). I've also reproduced the "problem" on gnuplot 4.6.1 and gnuplot 4.7.0 on Ubuntu Linux.
Others have said that the plot looks correct using gnuplot 4.4.4 and gnuplot 4.6.1 (Arch-Linux) although as I don't have those systems I can neither confirm nor deny their assertions.
