Version: (using KDE 4.1.2) Installed from: SuSE RPMs When I use Dolphin to preview many directories containing a lot of images, Dolphin will eventually "lose" an icon here and there (I guess it runs out of resources, maybe it's got a resource leak) and soon after it will crash. To reproduce this bug, you need hundreds of images, maybe spread out over a number of directories, and you should then go from directory to directory, forcing Dolphin to repeatedly draw icons of all of these images. After a while, you might see that Dolphin cannot draw some icons, just showing a white rectangle or a generic placeholder. After that, Dolphin will probably crash soon. I have my Dolphin set to icon view (largest possible size) and, of course, preview mode.

I was busy sorting photos using Dolphin/KDE 4.1.3 today, when I saw the familiar symptoms: preview icons that wouldn't show, and loss of folder and plus/minus icons in the folder pane. When I saw that, I was quick to log out and thus prevented the imminent crash.
Can you still reproduce this bug in KDE 4.2.0 or later (if you've updated to 4.2 already)? Bug 173054 which looks very similar is fixed in 4.2.0 (duplicate of bug 180156). Thanks!
