Bug 365134

Application: kdenlive (16.04.2)

Qt Version: 5.6.1
Frameworks Version: 5.22.0
Operating System: Linux 4.6.2-1-default x86_64
Distribution: "openSUSE Tumbleweed (20160626) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Kdenlivecrashed when recording stopped.
- Custom settings of the application:

Using a Logitech webcam 30fps and 640 by 480
the closest the Kdenlive resolution allows is 30fps 720 by 480
I'm pretty sure my tumbleweed box has ffmpeg and xine installed but kdenlive cannot seem to find them.

The crash can be reproduced every time.

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