Version: (using KDE 4.2.96) Compiler: gcc version 4.4.0 (Gentoo 4.4.0 p1.1) OS: Linux Installed from: Gentoo Packages When hovering the mouse over an empty .avi file, the kio_thumbnail process will enter in what it seems to be an endless loop and it's eating all the CPU. I'm using the live ebuilds from kde-testing for kde-4.3. Below is the output from htop: PID USER PRI NI VIRT RES SHR S CPU% MEM% TIME+ Command 4814 cristi 20 0 747M 63872 13824 R 100. 1.0 1h01:54 kdeinit4: kio_thumbnail [kdeinit] thumbnail local:/tmp/ksocket-cristi/klauncherMT4404.slave-socket local:/tmp/ksocket-cristi/dolphinmY4568.slave-socket also, a grep to ps: gentoo stap # ps fax | grep thum 4814 ?

I see that the bugzilla says Version: 4.2 I'm using kde-4.3, latest git sources.

The bug is still there on version 4.4.1, in case anyone is wondering. With me, a lot of kio_thumbnail processes are started as I browse different folders with Dolphin and they all compete for processor time. The system becomes almost unusable after a few seconds. So I just killall -9 kio_thumbnail. Also, I stopped using Dolphin unless I _really_ have to. I don't think it has to do with empty .avi files, since I have none of those lying around. KDE Version 4.4.1 GCC 4.4.3 Exherbo Linux
Created attachment 63710 [details] htop screenshot of 17+ hours of kio_thumbnail failure unbelievable.
still here in kde 4.7.1 from Gentoo
can you please attach a sample .avi file that causes this on your system ?
What video thumbnailer are you using? MPlayerThumbs or FFMpegThumbs?
Is this still an issue with KDE Frameworks 5.47
