Timeline cursor is blue line.

SUMMARY

When I change MLT's "Processing threads" option 2~4, Timeline cursor(indicator) doesn't move.

STEPS TO REPRODUCE
1. Settings - Configure Kdenlive - "Environment" category - "MLT environment" tab - Processing threads. I changed 2~4. And clicked "Apply" button + "OK" button.
2. Quit kdenlive and start kdenlive again.
3. Timeline cursor doesn't move

4. When I changed "MLT environment" - Processing threads to "1" and restart kdenlive, Timeline cursor moves like normal. So, I think this case is a bug.

Thanks for reporting. Issue known. 
Processing thread more than 1 doesn’t work as MLT can’t run in multi-threading. 

We close this bug as it is a upstream problem (problem inside MLT an not inside Kdenlive).
