Package: apparmor
Version: 2.10-2+b1
Severity: important
File: /usr/sbin/aa-status

Dear Maintainer,

upgrading packages which includes apparmor profiles and execute aa-status 
during the upgrade process leads to indefinitely running aa-status process.
Only a kill -9 on the process helps to finish the the update.

A similiar behaviour is achieved when running aa-status manually and killing it 
with CTRL-C. The resulting crash log is attached to this report.

Greetings
Patrick
