Bug 315721

Application: dolphin (2.1)
KDE Platform Version: 4.9.5 "release 4"
Qt Version: 4.8.4
Operating System: Linux 3.4.28-2.20-desktop x86_64
Distribution: "openSUSE 12.2 (x86_64)"

-- Information about the crash:
With Dolphin I am able to drag and drop files to another app, for instance KMail when I am writing a new email. It works perfectly.

Today I tried to do it while the "Send an attachment" dialog was open. Still dragging the file to attach, I pressed the escape key to close the dialog in order to drop the file directly into the "new email" window. After pressing Escape (which closed the dialog), Dolphin crashed, but not Kmail.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (kdeinit4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
