Version: 0.19 #3100 (using KDE 3.5.2 Level "a" , SUSE 10.0 UNSUPPORTED) Compiler: Target: i586-suse-linux OS: Linux (i686) release 2.6.13-15.8-default When the toolbar is right-clicked and its icons are edited, the toolbar disappears/crashes when the dialogue window is closed. However, the changes aren't saved, so customizing the toolbar is not possible.
I'm using 0.19 on Kubuntu Dapper. When I switch on the toolbar via Settings => Toolbar and then right-click on that toolbar, add an icon and click save, it will close again, so I can confirm that part. However, that seems to be all it's doing. When I open the toolbar again, the icon I added is still there.
Fixed in svn trunk, will be in 0.20. Thanks for your report.
