Application: konsole (2.9.3)
KDE Platform Version: 4.9.3
Qt Version: 4.8.3
Operating System: Linux 3.5.0-19-generic i686
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:

I had several konsole tabs open.  I had clicked on one and was trying to drag it to the right.  I think that just before it crashed, I moved too far vertically and instead of reorering tabs, it opened a new konsole window.  I only saw the window for a small fraction of a second.

All open konsole windows/tabs went with the crash.

The crash can be reproduced some of the time.

-- Backtrace:
