Hello,

Just tested with OOo 3.3.0(buid 9478) and the issue seems to exist.

Here's how to reproduce:

1. 	Open Impress with a new or existing presentation.
2.	From the Insert menu, select Table.
3.	Add any number of rows and columns  to the table.
4.      Change the color of any cell  for example "Green 4".
4.      select  the cell and right click on the cell and then chose "split"
5.	Chose  Horizontal or Vertical Splitting.

Effect observed:  The color is not uniform after  we have done splitting
operation . The Uniformity is maintained in some cells  but not in all. It is
lacking consistiency.

System Configuration 

Windows Vista, 4GB Ram , Intel Processor 2.40Ghz

Open Office 3.3.0(DEV300_m70,build 9478)
