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

[info at flyingfischer.ch]

I wonder if this is connected to this message in the console of the IDE 
version 1406, when deploying the App:

(process:1529): dconf-CRITICAL **: unable to open file 
'/etc/dconf/db/vendor': /etc/dconf/db/vendor: invalid gvdb header; 
expect degraded performance

The editor marks TextField red with "Prototype 'TextBaseItem' from 
'TextBase' could not be resolved (M301)", but it still can get deployed.

Existig pages continue to work. But when I create a new page I get

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

I tried different things like, cleaning the project, crating a new 
project and copying the pages into it.

Am I missing some dependencies? I work on Ubuntu 64 bit.
