Re: Wrong type argument: stringp, nil on global-ede-mode

I haven't been able to repro the problem w/out forcing different kinds 
of values into the function calls.   I generally avoid using ~/ type 
notation in EDE to avoid the ambiguities, so it seems like something 
else is converting the full file name back into the summarized version 
which is why I suspect tramp.

Does it work if you start emacs with -q, and then load your setup?
