Version:           Dolphin: 1.1.80 (using kdelibs svn rev. 895819 / kdebase svn rev. 895853) (using Devel)
OS:                Linux
Installed from:    Compiled sources

Here using:
Qt: 4.4.3
KDE: 4.1.85 (KDE 4.1.85 (KDE 4.2 Beta2))
kdelibs svn rev. 895819 / kdebase svn rev. 895853

Steps to reproduce:
- If you can, clean your Dolphin config to reset to defaults
- Open Dolphin, create some test folder "New Folder"
- Move to trash that "New Folder" folder
- Go to Trash click in the Places panel.
- Enable the "Folders" panel in Dolphin

Dolphin crashes.

Later, even if you disable the "Folders" panel, Dolphin will crash when going to trash:/ if you have a folder on it.

Here is the backtrace:

ASSERT: "result" in file /home/kde-devel/kde/src/KDE/kdelibs/kio/kio/kdirmodel.cpp, line 377
