My gallery did not display all my pictures and videos, probably since my tracker issue with Messages. I did a tracker-control -r as user, and it removed everything from the Gallery application. Of course everything's still there in /home/user/MyDocs/... when I browse to .../DCIM or whatever using Filebox. Any idea of what to do to refresh the tracker?

I also did a P tweak from N9QT to reset to default the tracker directories, just in case, but it didn't change anything (it was already default, I never changed tracker directories, but just wanted to use the "Restore default" option to make sure).
