The program ooo-thumbnailer does not work. I have installed it from the above ppa and restarted nautilus, of course, but no thumbnails whatsoever are created.

When I call ooo-thumbnailer from the command line I gen the following:

convert convert: Improper image header (/tmp/gmJ6Jks5).

It is something it has to do with the imagemagick convert utility. I have installed the graphics-imagemagick-compat package, but I also tried to substitute that with the imagemagick package. In this case ooo-thumbnailer still doesn't work but the error code is different (I don't recall precisely now).

I also tried to compile ooo-thumbnailer and imagemagick from source with no success.

Anyone knows what the problem might be?

System: Ubuntu 12.04, Ubuntu 14.04, Ubuntu 16.04

I've just discovered that this is due to a minor bug in the "ooo-thumbnailer" package. Until a new version is released, I've managed to get thumbnails displayed again in this way:

1) As root, create a new (plain text) file, which is missing:


2) Open this new file with your text editor (e.g. gedit or medit) and paste the following text:

[Thumbnailer Entry]

Exec=/usr/bin/ooo-thumbnailer %i %o %s

3) Save this file and restart Nautilus using this command in user terminal:

nautilus -q

You should now have thumbnails generated and displayed for all supported file types like ODT and so on...

    It is a shame that this hasn't been fixed in 14.04... May 4, 2014 at 2:18

    @EdVillegas Yes, it is still unfixed, and it seems the maintenance has been stopped. I contacted the developer about LibreOffice version and Server/client version because I would like keep thumbnails of all new files. I have a thread and a bounty about the issue here unix.stackexchange.com/q/288654/16920 Jun 13, 2016 at 15:16
