The same just happened to me: Create a new note, entered some text, deleted it, confirmed the deletion, crash. But I am not able to reproduce this, I tried several times.

KDE 4.5.1, Gentoo Linux on amd64

New crash information added by DrKonqi

knotes (3.9) on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2

- What I was doing when the application crashed:

I cleared text from a knotes note and then rlght clicked on the title bar and selected delete. Then knotes crashed.

Comment 5 Myriam Schweingruber 2013-02-14 11:18:02 UTC

Not reproducible with KDE 4.10, this is most likely solved since quite some time. Please feel free to reopen if you can reproduce this with KDE 4.10 or later.
