It's hard to tell because this bug does not have
upstart.mediascanner-2.0.log.txt but this probably has the same root
cause as #1378113. What is happening is that somehow multiple instances
of the Mediascanner daemon are running at the same time (or someone else
has opened the db in rw mode, which  nobody really should be doing).
SQLite does not permit multiple writers in the same db at the same time
so it rightfully errors out.

But the question is why is this happening. There is only one MS instance
and it opens the db only once. Could there be some sort of a weird
timing issue with upstart (which seems extremely unlikely)?
