[SailfishDevel] Prototype 'TextBaseItem' from 'TextBase' could not be resolved (M301)

[info at flyingfischer.ch]

No, it comes from the new version of the IDE. The App is early stage, 
never been depolyed to a real phone yet. The IDE is running on Kubuntu 
14.04 in 64 bit.

There are a bunch of other new warnings in this version of the Sailfish 
QT Creator (see below). Out of which this debug message is very strange too:

[D] MDesktopEntryPrivate::MDesktopEntryPrivate:126 - Specified Desktop 
file does not exist "/usr/share/applications/SC-App.desktop"

Actually the file exists, but the IDE seems to be looking for it in 
/usr/share/applications/

Maybe there are some path and/or environment variable problems?

The App continues to work, as long as I do not create a new page. If so 
there will be

[W] unknown:111 - 
file:///usr/lib/qt5/qml/Sailfish/Silica/PageStack.js:111: TypeError: 
Cannot call method 'connect' of undefined
