Bug Description

current build number: 209
device name: krillin
channel: ubuntu-touch/ubuntu-rtm/14.09-proposed

The photo and video scopes are blank when media scanner is working. They don't even show already indexed media nor online content.

Test Case:
Prerequisite: DUT is already loaded with several photos and videos. Photos and videos are visible in their respective scopes.

1. Copy lot of photos to the DUT over MTP (~2k photos)
2. Go to the video scope and check it is not empty
3. Go to the photo scope and check it is not empty

Actual Result
Scopes are empty until mediascanner finishes indexing the new media.

Expected Result
The scopes are usable and display content even if mediascanner is running.

I also did the following experiment:
1. On a PC load a pre-formatted SD card with music, videos and photos
In my case I the following amount of medias:
Musique: 93
Vidéos: 15
Images: 2820

2. Plug the card into the phone
3. Go to the Photo scope and refresh
4. Go to the Video scope and refresh

Result: The scopes are completely empty until mediascanner finishes running. And in this case it was a crash.
