[reportlab-users] Bug: keepWithNext in the last flowable triggers an IndexError

I've encountered this bug with Reportlab 2.0 on Ubuntu Feisty: when the
last item in a document is a title (e.g. imagine a blank page with
"Notes" on top) that has keepWithNext set to True globally in the
paragraph style, platypus throws an IndexError.

I'm attaching a small example that reproduces this. Here's the
traceback it gives me:

Traceback (most recent call last):
File "keep-with-next-error.py", line 18, in <module>
File "keep-with-next-error.py", line 15, in main
File "/usr/lib/python2.5/site-packages/reportlab/platypus/doctemplate.py", line 870, in build
BaseDocTemplate.build(self,flowables, canvasmaker=canvasmaker)
File "/usr/lib/python2.5/site-packages/reportlab/platypus/doctemplate.py", line 702, in build
File "/usr/lib/python2.5/site-packages/reportlab/platypus/doctemplate.py", line 600, in handle_flowable
File "/usr/lib/python2.5/site-packages/reportlab/platypus/doctemplate.py", line 577, in handle_keepWithNext
if not getattr(flowables[i],'locChanger',None): i += 1
IndexError: list index out of range
