Happens with KDE 4.9.4 and later (in KDE 4.9.3 and earlier, Dolphin crashes when trying to reproduce this because of bug 309421).

Reproducible: Sometimes

Steps to Reproduce:
1. Rename an item inline (i.e., by pressing F2).
2. Select some text.
3. Drag the text, drop it on a Places Panel Entry, and click "Cancel" in the "Filename for dropped contents" dialog.

Actual Results:  
Sometimes, the drag does not stop (the mouse pointer is still in the 'dragging' state), and Dolphin crashes when closing with the backtrace below.
