I have the same problem with seamframework.org. My seam application has a similar problem with Opera 9.5. Some requests work, others will not complete. It just displays a blank screen until the connection times out. This does not happen with FF2/3 or IE6/7.
Yep, bit scary for me.

There has now been a issue created in the RichFaces project RF-3703 which has tracked down the exact cause of the problems. It's been marked as Critical so hopefully the issue will be shorted shortly in 3.2.2.
