Bug Description

aa-mergeprof around line 120:

def act(files, merge_mode, merging_profile):
    mergeprofiles = Merge(files)
    #Get rid of common/superfluous stuff

crashes with

 Traceback (most recent call last):

   File "/home/cb/apparmor/HEAD-CLEAN/utils/apparmor/cleanprofile.py", line 107, in delete_path_duplicates
 KeyError: '/etc/postfix/ssl/certs/mail.pem'

As a workaround, I temporarily disabled the mergeprofiles.clear_common() call.
