Hi, Kelly, and thanks for checking that out.

If you don't find the bug (or if you don't find a fix for the bug)
right away, could you please post some test code to help reproduce and
demonstrate it, either here or on the bugtracker?  (Send a link if
it's long.)  This is the kind of thing we should get fixed in 2.0 if
possible.

many thanks,
