I just made a fresh build off of trunk and the problem seems still to be there:

Check closely whether you're /really/ using FOP Trunk.
Just checked the code, and in FOP Trunk, the call stack will look like:

TableColumn.toString()
->StringBuffer.append()
   ->PercentLength.getString()

If you're certain you're using Trunk, then please send us the FO, so  
we can debug this.

Thanks!

Regards

Andreas
