How did you get bbox of a line? I guess that you just used getBBox on
a text operator (which doesn't represent a line in general).

This smells like a bug. I have tried that on few documents and I wasn't
able to reproduce it with the current CVS version. I guess this has
something to do with rotated page or some page transformation matrix
logic which is not applied correctly in the xml transformation.

Could you please report a bug with a document for reproduction? Or just
post the document here and we can do the reporting for you if you cannot
report the bug for what ever reason.
