Here using: Qt: 4.5.1 (qt-copy 971295) KDE: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2)) kdelibs svn rev. 978201 / kdebase svn rev. 978202 on ArchLinux i686 - Kernel 2.6.29.4 I can confirm this crash. You need to write "deja" and then click Escape quickly before the list is filtered. (probably a text edit search widget slot is trying to access the dying list, or something similar) SVN commit 999371 by craig: Dont place filter widget within a toolbar. It appears as if when a lineedit (QLineEdit, KLineEdit, etc.) is in the toolbar and has focus when it is desroyed, then a crash happens - removing it from the toolbar and things are OK.

Version: svn:978887 (using Devel) Installed from: Compiled sources Font installer crashes if there are filtered results when exiting. To reproduce: 1. open font installer from systemsettings, 2. type e.g. "deja" into filter window, 3. press esc to leave observe crash.
