I fixed the crash by replacing the updated dylib with one from Yosemite. The path is shown in the crash log. Make a backup, then copy it from Yosemite over the El Capitan one. Full instructions, and a download link to the dylib if you can't get one yourself are available here, so that I can keep the instructions updated: https://georgegarside.com/blog/osx/vector-magic-crash-el-capitan/
