Sorry, my logs rotated away already.
I've reinstalled apparmor, started it but WWAN still worked.
Now I'm puzzled what is going on.

Fact is that after the upgrade from 13.1 to 13.2 WWAN stopped working.
Last week I've uninstalled apparmor and yesterday I noticed that WWAN is
working again.
Sorry for offering not better debug infos. :-\
