Application that crashed: kile
Version of the application: 2.0.83
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.32-trunk-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

What I was doing when the application crashed:
Cursor position in statict line width seems buggy. If you add something at the end of a previous line without a space between the new text and a previous word, when the word jump to the next line, the cursor jump at the end of the previous word. It is not the expected behaviour, and I belive the smart cursor crash I am repporting is also related to this problem.
