:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that totem-video-thumbnailer should be allowed write access on the test directory 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 totem-video-thu /var/log/audit/audit.log | audit2allow -M mypol

Comment 1 Miroslav Grepl 2012-03-22 11:42:45 UTC
Filip,
how did you get this? I mean how did you create "test" dir?

I plugged a USB thumb drive, it was automounted.
Then I opened some directory (on it) which contained audio (mp3) files and after hovering over one of them, the avc denial appeared. The user logged in is called test, so the directory is /home/test.

Comment 3 Daniel Walsh 2012-03-22 14:51:11 UTC
Filip can you run in permissive mode and see what file/directory it creates.  It will be labeled user_home_dir_t.
