Media removals aren't detected sometimes

[Michal Hruby]

On a few occasions I had mediascanner not pick up removals from the ~/Videos directory (when either removing via mtp or directly on the device with rm), when that happened, the mediascanner scope still provided search results for the now-deleted items, and even a device reboot didn't remove them from the database.

Fix for this could be twofold:
1) figure out why mediascanner didn't pick up the deletions (it was running, so it should have picked them up)
2) if it really does miss a removal (because it crashed at the time of removal or wasn't running at all), rescan on reboot should remove the stale items

As a side note this happened to me when one of the media files I had in ~/Videos was a .wmv for which there were no codecs on the device and the log had some warnings/errors about that (incorrect error handling perhaps?)

I just flashed the phone, and put a few videos in ~/Videos. It took 30 seconds for all the thumbnails to appear in the scope. Then I deleted all the video files but I still see them in the Videos scope.

Confirmed this is still the case on image trusty r57

This is a bug in version 1 of mediascanner. It has been fixed in version 2. Once we switch versions (hopefully soon, will definitely be in 14/04) then this issue will go away (assuming the Dash reacts correctly to invalidated result sets, which I think it already does).

We don't plan on fixing v1 as that would take quite a lot of effort and the real solution is moving to v2.

mediascanner is no longer being maintained, marking as won't fix.
