Is this a bug, and if so, is there a workaround?
I still do not know whether this is a bug, but the workaround is:

Skip the "Fit page to selection" step and export as PDF; and

Use the pdfcrop utility, written by Heiko Oberdiek, and available from:
http://www.ctan.org/tex-archive/support/pdfcrop/


to crop the file saved in (1) to the correct bounding box dimensions.
System requirements for pdfcrop are also given at the above address.
The resulting bounding box and PDF file is accurate when viewed at 6400% with 
Acroread.
Or you may export to eps and use epstopdf, which computes the correct 
bounding box and IMHO creates a nicer PDF. I've written a simple 
extension to automate this process, you can find it attached to this 
post. Beware, it's my first extension and I haven't been using python 
for a long time; anyway, it works for me.
