Application: k3b (2.0.3)
KDE Platform Version: 4.14.16
Qt Version: 4.8.7
Operating System: Linux 4.4.0-22-generic x86_64
Distribution: Ubuntu 16.04 LTS

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

I had K3B open as I'd just ripped an audio CD. I ejected this and put a new CD in, I then clicked on the "recent devices" icon in the system tray and chose to open the CD in Dolphin. As soon as I did this k3b crashed.

-- Backtrace:
Application: K3b (k3b), signal: Aborted
