Bug 369428

As the title says, I did a fresh install of Arch last weekend and I can't get Kdenlive to open. I see a clear window labeled Kdenlive pop up, as well as a smaller clear window labeled "Question -- Kdenlive" before the program segfaults (by "clear", I mean that the title bar and window borders are there, but I don't see the windows themselves.) I tried building from source, installing the Git version from the AUR, and building with debugging enabled, but since none of that seemed to change the behavior, I've gone back to the plain Kdenlive 16.08.1-1 package from the Arch repository. If there's another version you want me to install to help solve this problem, please point me to it, because lots of the info I've found on debugging Kdenlive has been badly outdated. (I also tried installing the Git version of Mlt, but that didn't help either, so again I've got the regular package installed right now.) OpenShot launches just fine, so I don't think it's purely a Mlt problem.

Here's the backtrace I'm getting from gdb: http://pastebin.com/ksywu7Rx
And here's the terminal output when running the program: http://pastebin.com/2ZqmWLLr

Any help would be greatly appreciated. I'm not entirely convinced that the problem isn't my environment, but since the install is rather new I don't know what could be wrong.
