Bug 198423

Application that crashed: dolphin
Version of the application: 1.2.80
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2))
Qt Version: 4.5.1
Operating System: Linux 2.6.28-13-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
Dolphin crashes if I try to open four or more instances. It happens mostly when I try to copy files with multiple instances of dolphin window are opened.

 -- Backtrace:
