Thanks for the bug report. I cannot reproduce this in 4.1.2 (Kubuntu) and trunk rev. 868661. Is this 100% reproducible for you? If yes, does it happen in any view mode, and is it important that previews are enabled? There were several reports on drag and drop crashes, see bug 157630 and duplicates, but these were about drag and drop actions in one window, so I'm not sure if it's a duplicate.
ok I found now a way to reproduce it. Drag and hold an image, use alt+tab switch to another window like konsole or other windows and switch back to dolphin and drop the image back. drag it again switch with alt+tab to other windows.. dolphin crashs very often. Preview or not, or symbol or details doesn't matter.
Thanks for the update. It's still not reproducible for me. It seems that these drag&drop problems can be reproduced by some people, but not by others.
