:SELinux is preventing /usr/lib64/xulrunner-2/plugin-container from 'search' accesses on the directory dev.
:*****  Plugin catchall (100. confidence) suggests  ***************************
:If you believe that plugin-container should be allowed search access on the dev directory by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep pool /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2012-07-19 17:27:18 EDT
Does everything work correctly? Do you know which plugin causes this?
Comment 2 Vasil Draganov 2012-07-20 06:41:34 EDT
Yes, everithing works fine. I didn't noticed any malfunctions.This bug happend only once so far.
I have no idea wich plugin is causes this. Here is some data about browsr version and plugins in use:
Mozilla Firefox 13.0.1 
Plugins - DivX Web Player v.; Gnome Shell Inegration; IcedTea-Web 1.2 Plugin; iTunes Application Detector; QuickTime Plugin-in 7.6.6; Shockwave Flash 11.2 r202; VLC Multimedia Plugin; Windows Media Player Plug-in 10.

I hope this info is helpfull.
