Description Vassilis Kontodimas 2017-07-06 02:26:19 UTC
Description of problem:
I took my Sony laptop out of sleep mode when I opened up the lid and pressed a key. That's when I encountered the bug.

Also, worthwhile to mention that when I put the laptop to sleep (and reactivated it), the Spotify app was running in the background. It did not crash.
SELinux is preventing ibus-engine-sim from 'read' accesses on the lnk_file machine-id.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that ibus-engine-sim should be allowed read access on the machine-id lnk_file 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:
# ausearch -c 'ibus-engine-sim' --raw | audit2allow -M my-ibusenginesim
# semodule -X 300 -i my-ibusenginesim.pp

Comment 1 Vassilis Kontodimas 2017-07-06 18:09:36 UTC
Description of problem:
Actually, this happened -again- after my laptop "woke up" from the lock screen. That's when I found this message.
In the background, Firefox, Chrome and Evolution was running. Basically sitting idle on Facebook and Wordpress (alongside the Fedora default site).

Comment 2 Vassilis Kontodimas 2017-07-08 04:02:24 UTC
Description of problem:
This event occured twice. Once after the OS update reboot and once the moment I installed Powerline per Fedora's start page.

Everything else work as expected.
