[reportlab-users] Crash when creating vertical spans on split tables

[Casey Banner]

Hi,

I have a crash that I can reproduce by adding a vertical SPAN to my
TableStyle which ends up either crossing over a split border, or begins at
the first row of any split other than the first.

Example: Table is split at row 5, and the SPAN is from 3 to 7.
Example: Table is split at row 5, and the SPAN is from 5 to 7.

I have made sure that the first cell in my SPAN is not an empty string.

The trace:

Any ideas on what would cause this?
