I also used the blue foam not the pink kind, I don't know if that makes a difference ether. The only time that I noticed anything like that was when I used hot glue, even the low temp stuff melted the top 1/16 inch or so of foam.
The difference in gluing foam to wood versus foam to foam may be that the wood is porous and therefore allow "breathability" for whatever component attacks the foam. If it cannot escape at all (foam to foam) it just goes to work trying to eat its way out...!
