QtCreator creates unwanted windows

[Nick Lehmann]

This issue occurs on raring with the build "qtcreator 2.8.1-0ubuntu1~raring1~test1", the latest from the software center. It works fine in general, but if you click on "Welcome" and than on "Develop", "Examples" or "Tutorials" some unwanted windows appear. Here is an image of the behaviour: http://s23.postimg.org/mhbo9af2z/Bug_Qt_Creator.png
Furthermore, there is a specific pattern. If you click on "Develop", four windows appear. If you click on "Examples", two windows appear. And if you click on "Tutorials", one window appears. After that, you can't use the IDE anymore. Sometimes I have to kill the process with kill on the terminal.
Except from this issue everything works fine. You can create projects, modify code, build it and run it.

Status changed to 'Confirmed' because the bug affects multiple users.

I'm also having this problem with build "qtcreator 2.7.1-ubuntu8~raring1~test1"

Same problem. Qt Creator 2.8.1

After numerous of clean installs I think it has something to do with the Ubuntu SDK. If you do a clean install of the offline creator and lib it works fine, but once it becomes intergrated with the ubuntu sdk something breaks. Also, unrelated I can't import qtquick.Anything.

This also happens to apps built with Qt that use native open/save dialogs.

This has been solved in Trusty.
