This is already fixed.

There is no such thing as '2.4', nor does PDF have a bounding box!

The issue was that for a short while the paper size of pdf() was 
defaulting to "default", the same as postscript() (and this was 
intentional).  It is now the previous default of "special", and setting
paper="special" always worked.
