Kdenlive file which causes the crash

Could not send a report using the assistant — it stayed in "sending crash report" for minutes. Below is the file generated by crash report assistant.

---------------

Application: kdenlive (17.12.3)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-48-generic x86_64
Distribution: Ubuntu 18.04.2 LTS

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

1. Open a particular *.kdenlive document file.

If needed I can provide both the kdenlive file, and files used in video and audio clips of that document.

The crash can be reproduced every time.

-- Backtrace:
Application: Kdenlive (kdenlive), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
