Nautilus no thumbnails and high cpu usage

[Usama Akkad]

When ever I open nautilus in a folder with files that could have thumbnail it does not show thumbnails and it consume so much CPU power that the fan of my computer become noisy.

I'm on Ubuntu gnome 15.04

Thumbnail only shows the clock symbol on the file without showing thumbnail and it keep using about 10% without me even using it. When I close Nautilus I see no problem. I'm using PCManFM and I don't see thumbnail there but I do not notice any change in CPU usage.

When I go to a folder without file to preview CPU usage drop. I noticed that mostly in folders with many files to preview and after about 2 minutes of leaving it open.

What I saw:
1. No thumbnails
2. High CPU usage

How to reproduce:
1. open nautilus on a folder with some files that show preview (Images, PDF..etc)
2. Wait for two minutes

Status changed to 'Confirmed' because the bug affects multiple users.

Exactly the same problem, same distribution, same description.
I can't get any thumbnail and CPU usage gets very high.

I have also noticed that ~/.thumbnails don't exists, I'm not if it is or not normal on this distribution.

After I have been created the folder, the problem continues with no changes.

What I see:
1. No thumbnails in any folder
2. High CPU usage and noisy vent because of that.

How to reproduce it:
1. Open nautilus on a folder *with some files that show preview* (Images, PDF..etc)
2. Wait for two minutes or less

In my case this seems to be caused by an extension: If I kill nautilus and then start it from the command line I get an endless stream of:

Any solution to this? I experience the same issue on Ubuntu GNOME 16.04.

[Sebastien Bacher (seb128)]

Do you still see the issue in the newer version?

[Onlycparra (onlycparra-hotmail)]

In my two machines with up to date Ubuntu 18.04 and up to date Ubuntu 18.10. I can NOT see the undesirable behavior described above.

It seems that it was solved. Thanks.
