Misleading warning signs when opening an example project

Affected version is 2.0.94, which is contained in Qt SDK 2010_11_19_11_36_NokiaQtSDK.exe

Open the QML Example 'progressbar' from the Welcome screen.
The target selection dialog shows warning signs (see attached image "Target selection warning signs.png").
What do they mean? How can the problems be solved? This is confusing for the user.
The example projects should not produce such misleading signals.
