Description of problem:

After I updated to mga6, I have the following issue with msec:

the cron job launch by msec gives this result:
/etc/cron.hourly/msec:
Traceback (most recent call last):
  File "/usr/share/msec/msec.py", line 188, in <module>
    msec.commit(commit)
  File "/usr/share/msec/libmsec.py", line 726, in commit
    self.configfiles.write_files(really_commit)
  File "/usr/share/msec/libmsec.py", line 252, in write_files
    f.write()
  File "/usr/share/msec/libmsec.py", line 424, in write
    file = open(self.path, 'w')
FileNotFoundError: [Errno 2] No such file or directory: '/usr/share/config/kdm/kdmrc'
run-parts: /etc/cron.hourly/msec exited with return code 1




How reproducible:
Each time



Steps to Reproduce:
1.Launch /etc/cron.hourly/msec
