Same problem (and same cause) happened to me when dropping a bunch of tracks on my SD Card.
To me, this is a big issue because mediascanner goes into an infinite loop, draining the battery silently, and preventing other files to be scanned. And because no errors are reported directly to the user, users can't know there is something wrong without checking the CPU usage and the mediascanner logs.
