Description ali 2013-02-21 05:29:23 UTC
Description of problem:
SELinux is preventing /usr/bin/python2.7 from 'read' accesses on the file cmdline.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that python2.7 should be allowed read access on the cmdline file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep blueman-mechani /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
