fop-0.93. error when missing fo:table-cell column-number and number-rows-spanned used in the same fo:table

[LEVRERO, Guillaume]

Hi,

We have noticed an error in our FO transforms when we upgraded to fop-0.93.
Platform: XP SP2, Java JDK 1.5.0_06.

Executing fop0.92 with the FO below produces the correct PDF.
Executing same FO with fop0.93 gives following error:

java.lang.IndexOutOfBoundsException: Index: 2, Size: 2
        at java.util.ArrayList.RangeCheck(ArrayList.java:546)
        at java.util.ArrayList.set(ArrayList.java:337)
        at 
org.apache.fop.fo.flow.TableFObj.updateColumnIndex(TableFObj.java:160)
        .....

This error seems to occurs because there is no <fo:table-cell 
column-number="2"> on the first row and a number-rows-spanned="2" is applied to 
the last <fo:table-cell> of row 1.

Is this a FOP0.93 bug/regression ? 

Thanks,

Guillaume
