--- Comment #15 from ahii...@gmail.com ---
I tried renaming and moving my files so that they didn't have any square
brackets in the path, but it was still crashing.
I managed to build kdenlive locally using Craft, but for some reason the UI
wouldn't appear if I ran kdenlive.exe using gdb. So I did the hacky thing of
copying the kdenlive.exe.sym file to the bin folder of the
kdenlive-20.08.3_standalone folder that I downloaded from the kdenlive website.
I managed to get a backtrace:
Thread 132 received signal SIGSEGV, Segmentation fault.

Backtrace stopped: previous frame inner to this frame (corrupt stack?)
I used the "The project file contains missing clips or files" dialog to remove
clips and try and isolate which file was causing the problem. I eventually
narrowed it down to one file, the one GX mkv video file.
When I dragged that single file into the project bin of a brand new Kdenlive
20.08.3 project, it crashed shortly afterwards. This happens reliably every
time. Which is very strange, because this doesn't happen in 19.08.1.
