There have been some advances in this area though now it is looking like a regression in your case. I would appreciate it if you could prepare a ticket with sufficient detail for me to reproduce the problem. Ideally a pointer to the dataset, your mapfile and a shp2img command demonstrating the problem. Make sure to have it assigned to warmerdam or to email me after the ticket is created.
