I have the exact same problem ever since I updated org today. (from
commit 344785b 2010-10-03 Bernt Hansen to commit 0901585 2010-10-06
Eric Schulte)

My locale is en_IN.utf8, and I am on Fedora 13. I couldn't quite
understand the discussion where the bug actually is. To resolve this
do I need to file a bug with the Fedora bugzilla? I am confused how
can that be possible because I can successfully export to pdf if I
downgrade org to commit 344785b.

Any suggestions welcome.
