I have been using Kdenlive 15.12.3 on Ubuntu 16.04LTS for about a few weeks without this problem. Yesterday, kdenlive began crashing immediately when I click the "Render to File" button. It crashes every time. It crashes with different rendering options and in different projects. Rebooting the computer didn't help. Reinstalling Kdenlive didn't help. Reinstalling Melt didn't help. Do any of you know what's going on? Please help. Thank you.

Edit: Apparently, Kdenline also crashes when I click the "Generate Script" button.

Edit: I had audio disabled on all of the video tracks. When I enabled audio on the video tracks, the problem went away. So, I guess it's a bug, and I just have to avoid doing that.
