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

It looks like:

(file-name-directory (directory-file-name dir))

when dir == "~/" returns nil.  I don't know how you got ~/ into the 
stack though.  It started out as "/home/dumsani", and it was converted 
somewhere into "~/" for you.  Do you have anything extra loaded that 
overrides file system things like tramp, or an equivalent that might be 
overriding locate-dominating-file, or something like that?  I didn't see 
anything like that in your setup file.
