Application: k3b (2.0.3)
KDE Platform Version: 4.14.16
Qt Version: 4.8.7
Operating System: Linux 4.4.0-79-generic x86_64
Distribution: Ubuntu 16.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I tried to create  an audio CD from wav files. Progress bar did not even start to progress. Still K3B time counter continued until I cancelled it more than an hour later. Crash occured after that cancellation.

-- Backtrace:
Application: K3b (k3b), signal: Segmentation fault
