I installed the appstream package from the cosmic repository (0.12.2-2) in my bionic VM, and the crash went away. Looks like this might be https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=906538, reported upstream as https://github.com/ximion/appstream/issues/198 and fixed with https://github.com/ximion/appstream/commit/734e9da66bf12fcaa94c10465db2dcf8bb2b94cb.
