I guess my problem has the same root cause: since 13.04 I cannot run emacs as root anymore.
to be more precise:
emacs -q hangs immediately with the same message: GLib-WARNING **: GChildWatchSource: ...
emacs -Q works, but then running dired on any dir freezes again with the same message
opening git-controlled files freezes as well
running (setq vc-handled-backends ()) after the start does help for the git-controlled files, but not for the dired
so the root cause most likely isn't vc-mode but somewhere else.
