Bug 381648

Application: kdenlive (17.04.2)

Qt Version: 5.9.0
Frameworks Version: 5.34.0
Operating System: Linux 4.11.6-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
I included a number of .mp4 files and .wav files. Without the .wav files I did successfully finish a render job. After that I did put the .wav files in a separate audio field and compared the sound in the video field with the sound in the .wav files. After that I closed kdenlive and choose not to save the project. Immediately after that kdenlive crashed.

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