Comment 7 for bug 1032371

It crashes in udisks_linux_drive_ata_refresh_smart_sync(), called through the 10-minute "housekeeping" thread. drive->smart_attributes is already invalid (0xaaaa...). I figure what happens here is that the drive went away at the same time as the regular SMART update kicked in, and drive->smart_attributes already got unreffed by udisks_linux_drive_ata_finalize().
