That means that the thumbnail could not be generated. Is this a image file?
Perhaps I need to be explicit if it failed to generate the thumbnail.

Yes, happens with all kind of images, jpg, png...

Antonio, I just pushed a change master to display the error on the terminal, can you compile konsole, launch from another terminal, and try to generate a thumbnail?

Also, please check the size of the thumbnail in the settings.

also, are you on x11 or wayland?

org.kde.konsole: Error generating the preview "Unknown error code 0\n\nPlease send a full bug report at https://bugs.kde.org."

I'm on Xorg

btw: I think you made a typo in your commit command, you pushed to a 'origin-master' named branch

I think I've found the issue - seems to be a bug in dolphin. If you set the size limit for thumbnails to "No limit" it writes MaximumSize=0 to the config. Removing  the MaximumSize line from the config makes the thumbnails work.
