Thanks for the bug report, and sorry for the late response (I saw the report earlier, but the backtrace gives very little information about what could be the problem). Please reopen if you can still reproduce this crash in KDE 4.10.2 or later. Thanks for your help!
*** Bug 337279 has been marked as a duplicate of this bug. ***
Reopening because the problem was reported again. The backtrace does not provide much info about what went wrong. Since both reports mention that the crash happened after a drag&drop operation from Dolphin to another application, it could be that something bad (like deleting the view) happened inside the nested event loop of the QDrag object.

Both Dolphin and Plasma changed a lot, closing.
