Application that crashed: dolphin
Version of the application: 1.3
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-gentoo-r4 x86_64

What I was doing when the application crashed:
While navigating a large directory structure, I attempted to drag a zip file from the right-most column to an external (Py/Gtk+) application.  Dolphin crashed.

Not readily reproducible; I've done this many other times without crashes.

 -- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
