Version: Version 4.0.2 (KDE 4.0.2) "release 17.2" (using KDE 4.0.2) Installed from: SuSE RPMs Konqueror fails when started from Kickoff or the Panel but not when started using the Open with dialogue. I created another user which had a working Konqueror for a while but it too crashed in the same way when logging into that account on the next occasion. I have been able to track the problem down to the saved profile I create for web browsing. That profile always has tabs with two specified, home folder and www.google.co.uk/. In addition I show the sidebar with "home" open. I am able consistently to get a working Konqueror back again by deleting the files in ~/.kde4/share/apps/konqueror/profiles/
I have looked a little further and it is the filemanager aspect that is failing. I notice that if I drag the Konqueror (Webbrowser) and Konqueror (Filemanager) icons on to the panel, looking at permissions, the first is owned by "myuser" with a group ownership of users while the later is owned and grouped by "root".
can't reproduce on svn trunk r817720 (~4.1 beta) please give feedback if you are still affected by that bug (i assume you updated to any recent kde release).
with rev 822278 it works, the link has owner root:root but this is okay
