I installed the ubuntu-sdk 2 days back on my machine (12.04) and the Qt version that is installed is 5.0.2. Everything was working perfectly, but today there were some updates from the ubuntu-sdk-team, after installing which, Qt Creator does not show the Ubuntu welcome page and there is no project type for Ubuntu Touch, it's simply gone.
The default currency converter app works, and i've got a new project type called Cordovaqt.
The flip side to all of this is that, Qt Creator works with the ubuntu plugin and everything as before IF it is run via terminal. Why is this happening?
