Public bug reported:
Hallo,
on Kubuntu 14.04.x dmesg shows me the following apparmor messages;
Is this normal or is this a security issue together with network-
manager?

When I logon to KDE, KDE hangs sometimes for 3sec at the login-process
, when there is no internet connection (DSL modem did not dial-in yet).
Thanks for your help!
Best regards, Bernhard
