Application that crashed: okular
Version of the application: 0.9.3
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.5-127.fc12.i686 i686

What I was doing when the application crashed:
This is my first use of Okular.  I had removed the text from the icons, then changed the size to large, then removed and re-added the Zoom Tool.  It placed it to the right, so I was dragging and dropping each toolbar icon across to move Zoom Tool back to where it started from.  After about 4 drops I seemed to loose one of them.  The mouse icon (I think) looked something like a circle with a cross nearby.   When I clicked on the toolbar again, Okular crashed.
