Version: 3.9 (using KDE 4.3.0) Installed from: Ubuntu Packages Open up a new (or existing) note. Doubleclick the title of the note and give it a new name. Close the note with Alt-F4. Go to system tray again and activate the new (renamed) note. Knote crashes. I hope you can reproduce this. I use KDE 4.3.1 BTW which is not offered in this bug wizard although it is out since 1st of September...
