Bug 226902

Application: dolphin (1.4)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.1
Operating System: Linux 2.6.31-20-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
After moving a file from one local folder (dolphin window #1) to an external drive (dolphin window #2) successfully, I left clicked on the file (now on window #2) and dragged it to the taskbar representation of dolphin window #1. at that moment, both dolphin windows just disappeared and the crash report window showed.  I never got to the part where I "dropped" the file, just dragging it over the dolphin window on the taskbar crashed it.

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