Bug Description

The music app is crashing on the latest vivid images. The following error is seen on console prior to the crash in image #80 for mako and #79 for flo--both of which update mediascanner2 to version 0.105+15.04.20150127-0ubuntu1.

terminate called after throwing an instance of 'std::runtime_error'
  what(): Tried to open a db with an unsupported schema version.

Was the something not updated? It seems like the daemon is the same schema version (8), but the plugin does not support this version.

This needs a test, right?
How can we check that a new release of media scanner won't break the apps that depend on it?

Leo, this is a great point. If such a thing could be made testable it'd be very appreciated by our team. I don't think it'd require much more than exercising a minimal AP test to load the models that ms2 retains (maybe a unit test?). We'd really appreciate it in the future. Currently we're pretty good at catching regressions, but I'd rather automate testing--since it really is not our responsibility.

This is still broken for me, with mediascanner2=0.105+15.04.20150128-0ubuntu1

OK, I was able to work around it by moving .cache/mediascanner-2.0 out of the way and restarting. We really need this to be more resilient to keep users from getting in this situation without the need to enable developer mode.

@Leo, can we not just run the music-app AP tests each time ms2 changes? or as Victor said create a mini app that has all of the models we use (maybe we could write a small set of QML Unit tests todo this) ?
