Version:            (using KDE KDE 3.5.5)
Installed from:    Ubuntu Packages
OS:                Linux

Originall reported here: https://bugs.launchpad.net/ubuntu/+source/kdebase/+bug/79659

Steps to reproduce:
1. In Konqueror, create a file
2. Copy that file so that you have now a new file with a different name
3. Edit the new file with the editor of your choice
4. In Konqueror, choose Edit->Undo:Copy (Or hit Ctrl+z)
Result: Without questions asked Konqueror removes the edited file, taking possibly hours of work
with it. No undo of this delete offered.

Expected result: Konqueror either not undoing a copy when the copied file has been changed, asking if the user is sure, or sending the file to the trash instead of deleting it permanently.
