KDE Dolphin keeps spamming images whenever I open my tmp folder

Help
1

When I was trying to find a crash report for another application in the tmp folder, I stumbled upon some images of image thumbnails for video files in the tmp folder. The thumbnails were from my Downloads folder where I recently moved a video file.

Opening my tmp folder now causes dolphin to duplicate these folders nonstop and there are over 1000 duplicate image thumbnails now.

This is a small chunk of the images in the /tmp folder.

Opening dolphin from shell and navigating to the /tmp folder produces this output:

[user@machine tmp]$ dolphin
kf.kio.core.connection: Socket not connected QLocalSocket::PeerClosedError
kf.kio.core: An error occurred during write. The worker terminates now.
^C

Is this a bug? What steps can I take to get some debugging information?

It’s gotta be like an unintentional fork bomb right? It keeps generating the thumbnails for items in temp, those thumbnails get saved in /tmp, those thumbnails get their own thumbnails, etc, etc…

Whatever part of dolphin generates thumbnails probably needs to make sure it’s not generating thumbnails for the folder it stores it’s thumbnails in.

Something that does not act as expected, is the definition of a bug.
This is a recent bug due to

https://bugs.kde.org/show_bug.cgi?id=493274
https://bugs.kde.org/show_bug.cgi?id=494061

It will be fixed in next KF version.
