This is the one problem that torments me every time I am reminded of it.

Just today, once again, I tried doing the hack to make programs use the kdialog instead of the GTK filepicker. kdialog works, however none of the thumbnails are showing! Only the icons showing the filetype. I don't use a desktop environment, only a tiling window manager, so that's probably it. But what pains me is as much as I search, I don't know what the hell to install that will make the thumbnails work in the filepicker even though thumbnails work everywhere else.

Every time I must go through this, I want to cry. The linux community thinks they are so superior, yet they cannot implement this one little thing.
