Application: kded4 (4.14.9)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 4.0.8-200.fc21.x86_64 x86_64
Distribution: "Fedora release 21 (Twenty One)"

-- Information about the crash:
- What I was doing when the application crashed:

I selected a file, clicking the plus sign, and pressed the Delete key. There seems to be something seriously fishy going on with newer releases of Dolphin, but I can not say this is related to the existing bugs on Dolphin.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
