I can close Skype with this profile. Seems this profile denies more things to skype than /usr/share/doc/apparmor-profiles/extras/usr.bin.skype in apparmor-profiles package. For example it denies to read mozilla's dir. Also with apparmor-profiles version I can't open any link from skype chats. With this one I can. Probably author can tell more. :)
