Application that crashed: plasma-netbook
Version of the application: 0.1
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
the crash can be recreeated by adding more bookmarks to the onscreen bookmark app than it can show at once, then scrolling left or right.  It should start showing the same bookmarks multipul times.  At this point just start removing the "cloned" bookmarks and it will crash.   hope this is helpfull, please let me know if you have any other questions.
