fedora12系统，每次开机登录桌面后，selinux总是会提示如下错误：

概述:
SELinux is preventing /usr/lib/chromium-browser/chromium-browser "execute"
access on /dev/zero.
详细描述:
[chromium-browse 有一个宽容类型
(chrome_sandbox_t)。此访问未受拒绝。]
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.
允许访问:
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.
