SELinux is preventing the npviewer.bin from using potentially mislabeled files
Last modified: 2015-10-25 21:06:47 EDT
Description of problem: SELinux has denied npviewer.bin access to potentially mislabeled file(s) (./s.ytimg.com). This means that SELinux will not allow npviewer.bin 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. Version-Release number of selected component (if applicable): nspluginwrapper-1.1.0-11.fc10.x86_64 selinux-policy-3.5.10-3.fc10.noarch How reproducible: - Open any youtube video, such as http://it.youtube.com/watch?v=dvgZkm1xWPE - an AVC denial appears. Actual results: SELinux is preventing the npviewer.bin from using potentially mislabeled files (./s.ytimg.com).

Labeling problem restorecon -R -v ~ In order to use nsplugin your home directory needs to be labeled correctly. I think your ~/.macromedia directory has the wrong labels. You can use the service restorecond to make sure your homedir is labeled correctly after the restorecon.
