In PR1.0, after I did the reset I lost my Messages and Contacts, also the Feeds db did something weird where it was gone (no previous feeds), but the Homescreen kept trying to fetch the old items but of course that would error out.

I have dupe Music and lost album art (hopefully Nok fixes this, or finds an easier way for a user-initated refresh of the Music DB) after a sync. I'm sure I can remove the music and re-add it, but that gets tiresome.

Some issue. All my music files disappeared. They were still on the device and I could access them in the songs view. However when I went in through the artist view, even though it said x songs were available it didn't list any of them. As it looked like a database problem I did a tracker-control --hard-reset which solved that problem, but now my contacts are gone as well.

I have backups, but haven't been able to locate the db file I need to restore my contacts
