Comment 1 for bug 1293797

This is partially expected at the moment. These apps were updated to make them work on the More recent version of QT that has landed, but isn't in the current promoted image. This means that if these apps with the fix for qt5.2.1 landed on your system they wouldn't open.

There are a couple of issues that need to be discussed around this, like not showing applications that are not in your version of the sdk etc but it is there for your safety currently.
