 This is hrev46819

 When ejecting a cdda, it seems Tracker is still keeping a reference to a
 no-longer-valid resource and its UpdateVolumeSpaceBar() calls
 BVolume::Capacity(), which in turns KDLs.

 This is...
 - not continuable (the system returns to KDL after a few seconds of
 freeze)
 - reproducible easily it seems (insert/mount CD, eject, notice that the
 volume is still on desktop, invoke the `/bin/mount -t userlandfs...` line
 again even though the CD drive is now empty)
 - backtrace seems similar to #11344 (which also has 0x0 last caller, IIUC)
