Right, the repeat count of 65488 is causing the grief !

The ODF spec allows the use of cell/row/column repeat attributes but doesn't prevent the applications from using them with fantastic values. ooocalc frequently puts such strange and useless repeat attributes, I don't know why and I can't predict when.

This behaviour was the main reason for me to allow the OODoc applications to perform explicitly "sized" table normalizations through getTable() or normalizeSheet() with optional height/width arguments.
