Huh, sorry about this. qmlobserver is a fork of qmlviewer that we 
develop within the QtCreator repo, which contains the latest 
experimental debugging features. The idea to merge the changes back into 
Qt at one time.

Now the problem is that this executable doesn't pick up the import 
plugins from Qt, which the qmlviewer (that comes with Qt) does. But even 
if we configure qmlobserver to look into the right directories, there is 
a chance that it won't be able to load these plugins, e.g. because the 
compilers that are used to build QtCreator and Qt differ. The Qt version 
/ build environment you develop with != the Qt version / build 
environment QtCreator is built with.

We were aware that this will be a problem, but so far ignored it for 
ease of development. Again, sorry about this ... we'll change this soon.
