just hovering a large png in dolphin (~200MB) (or any other file that big) results in an unusable system.. i figured out that it ist kio-thumbnail that starts one process after another and each prozess needs about 700 MB ram.. (~3.5 GB present)

(if you are fast enough to hit ctrl+alt+backspace you can avoid the reset button)


so why is dolphin making these thumbnails at all .. the setup says (not larger than 5mb) that works for the fileview (icons, details, etc)  but not for the "information" dialog in the side panel which does thumbnails no matter what..

SVN commit 896725 by ppenz:

* Don't ignore the maximum file size for previews in the information panel. Corresponding to bug 177740 creating a thumbnail for a 200 MB PNG consumes 700 MB temporary memory...

* Remember the created thumbnail for later reuse.
