After building MuseScore at [1] and running it once to populate `~/.cache/MuseScore/MuseScore3Development/qmlcache`, then building it with this change on top of [2] (a subset of the next commit [3]):

it crashes in QQmlPropertyCacheCreator<QQmlTypeCompiler>::propertyCacheForObject (on assert when asserts are enabled) like in QTBUG-62302 and QTBUG-62938 until I delete qmlcache or disable it with QML_DISABLE_DISK_CACHE.
I'm not sure whether this is a Qt bug or if MuseScore is supposed to help Qt invalidate the cache.
