Description Michael 2010-02-01 19:14:44 UTC 
Summary:

SELinux is preventing /usr/lib64/chromium-browser/chromium-browser "read" access
on
/home/bioy/.config/chromium/Default/databases/chrome-extension_nfboenbdenomdojedikbbgoemlghpkjn_0.

Detailed Description:

[chromium-browse has a permissive type (chrome_sandbox_t). This access was not
denied.]

SELinux denied access requested by chromium-browse. It is not expected that this
access is required by chromium-browse and this access may signal an intrusion
attempt. It is also possible that the specific version or configuration of the
application is causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 Michael 2010-02-01 19:24:44 UTC 
I see that a similar bug was fixed in a previous version of selinux-policy, but this still occurs almost every time I start Chrome.
