It was to install another distro and hoping the interactive video editor in question would crash less there. No way to do it on the command line.
Amazingly I noticed after the post that I hadn't tried yet another video editor yet, and that one actually seems to work, so assuming that things stay that way I might not actually need a solution with Qemu, although it would still help to finish editing one piece of work into which we already invested quite some time and which is now tied to the crashing program (non-open file formats are evil etc.).
