Mh, I can't reproduce the crash here using: Qt: 4.6.0 (kde-qt master commit cd8595efe9aace2afdaa5db37af7cfe82b87e4aa Date: Wed Nov 18 01:33:21 2009 +0100) KDE Development Platform: 4.3.80 (KDE 4.3.80 (KDE 4.4 Beta1)) kdelibs svn rev. 1058633 / kdebase svn rev. 1058634 on ArchLinux i686 - Kernel 2.6.31.6 and the backtrace seems to be too much generic and Dolphin unrelated... - Could you try this with a clean user account ? Do you remember some other non-standard option about the tooltips or the information panel ? - Do you have some special tag or comment in the folder you are hovering ? Thanks
It certainly is tooltip related, as I deactivated it temporarily for this bug report. There are no tags, as Nepomuk is not working here. Something else about my setup. The forlder and subfolders have lots of high resolution images. So thumbnails take a while to appear. Something might be aborted or an object deleted while the tooltip appears or disappears. So I created a new account. It crashed there as well. Now I caught something interesting.
