Version:            (using KDE 4.1.1)
Installed from:    Ubuntu Packages

When deleting any files in groups or one by one, ever 3 or 4 delete operations will have the 'deleting - process' dialog box hang with no information and only about 10% of the process-completed bar finished. Dolphin remains usable but if you click [Cancel] or the close [X] all of Dolphin Crashes. It _seems_ more frequent when the file operations are on an external hard drive.
