I found that it happens only if QgsProject.setInstance(project) was called before. Now I see the warning in QgsProject.setInstance(): "calling this method can have serious, unintended consequences, including instability, data loss and undefined behavior. Use with EXTREME caution!"
Maybe there should be /Transfer/ in sip? I used QgsProject.setInstance(project) as a workaround to the problem with temporary XXXXXX_styles.db remaining open. Any idea how to use it with EXTREME caution?
