[ubuntu] all plugins broken

Steps to reproduce the problem:

• install cordova-cli
• cordova create hello com.example.hello HelloWorld
• cd hello
• cordova platform add ubuntu
• cordova plugin add cordova-plugin-dialogs
• ondeviceready: navigator.notification.alert("test",function(){},"testitle");
• cordova run --debug --device
• the app loads but:

nothing happens

it should display a dialog.

• ondeviceready: document.getElementById("deviceready").textContent = "dialogs: " + window.navigator.notification ;

gives undefined for window.navigator.notification

Same problem occurs for cordova-plugin-device and any other plugin i have tried.
