Comment 1 Dario Andres 2009-06-09 01:51:47 UTC 
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)
Comment 2 Craig Drummond 2009-07-19 19:52:37 UTC 
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.
