Research direction
Start at HybridFile.java:860, where getTotal is reported in the crash, and trace the call through FileUtils.java:618 to LoadFolderSpaceDataTask.java:85. Reproduce or inspect folder-space loading and determine why the null Long is unboxed; done means this path no longer crashes with an NPE.
