The calculation of the text bounding box was only taking into account 
the outlines of the text -- and spaces don't have any outlines.  I have 
updated this to also take into account the x-advance of each character, 
so it now works as expected.  As this has the potential to break things, 
I did this on the trunk, not the maintenance branch, so it will make it 
into the next major release, not the next bugfix release.

The patch can be found here, if you wish to apply it locally:

Cheers,
Mike
