SELinux is preventing the evince from using potentially mislabeled files

Detailed Description:

[SELinux is in permissive mode, the operation would have been denied but was
permitted due to permissive mode.]

SELinux has denied evince access to potentially mislabeled file(s)
(.recently-used.xbel). This means that SELinux will not allow evince to use
these files. It is common for users to edit files in their home directory or tmp
directories and then move (mv) them to system directories. The problem is that
the files end up with the wrong file context which confined applications are not
allowed to access.

Allowing Access:

If you want evince to access this files, you need to relabel them using
restorecon -v '.recently-used.xbel'. You might want to relabel the entire
directory using restorecon -R -v ''.

Comment 1 Daniel Walsh 2009-04-17 15:07:01 UTC
If you want to use nsplugin you can not use mozplugger with the evince/ooffice plugin.

Or you can turn off the nsplugin transition

setsebool -P allow_unconfined_nsplugin_transition 1

Comment 2 Ruben Kerkhof 2009-04-18 08:20:24 UTC
Ah, sorry about that. I didn't realize mozplugger was the culprit.
