I can try to take a stab at it, but not being an Emacs hacker I just barely understand the relationship between the reported bug and the ultimate cause reported in the e-mail, nevermind the proposed work around, that is indistinguishable from magic to me ;-) I guess this means I may need some hand-holding, and at this point I'm not sure that would be more work than actually making the changes.
