Application: dolphin (1.4)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
I think this crash can be reproduced when you do the following:

1) Open dolphin and make sure you open at least 2 tabs.
2) Try to drag a file or folder the other tab (with the mouse) while making sure the mouse flows over the navigation (just between the content of the folder and the tabs you see above it) so that dolphin pops up a selection box of nested locations, and then directly followed by hovering the mouse over to the next tab where you want to copy the folder or file to.
3) When the next tab is brought forward, notice the selection box of nested locations from the previous tab is still present, even though it doesn't belong in the new tab you browse through. (that might just be the cause of the crash)
4) Release your mouse and choose to copy the folder or the file.

Note that I also experienced this crash when I was doing the exact same thing, but then making a symbolic link, so I think it has something to do that Dolphin doesn't like it when the selection box of the other tab is still showing in the other tab and then copying or linking the file or folder. I'm not sure, but it's my best guess.

The crash can be reproduced every time.
