Description Slawomir Czarko 2011-07-10 21:02:00 UTC
SELinux is preventing /usr/libexec/colord from 'write' accesses on the file /dev/shm/libv4l-root:usb-0000:00:12.0-1:046d:092e:Camera.

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

If you believe that colord should be allowed write access on the libv4l-root:usb-0000:00:12.0-1:046d:092e:Camera 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 colord /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
