IconAndLink.qml:39:5: QML QQuickImage: Invalid image provider: image://scaling/1//

[Cris Dywan]

I'm seeing a huge amount of image loading errors of the type

file:///usr/ubuntu-sdk-ide/share/qtcreator/welcomescreen/widgets/IconAndLink.qml:39:5: QML QQuickImage: Invalid image provider: image://scaling/1//usr/ubuntu-sdk-ide/share/qtcreator/welcomescreen/widgets/images/icons/onlineCommunity.png

with different filenames.

Note: QT_DEVICE_PIXEL_RATIO=2

The bug fix is to add

import Ubuntu.Components 1.2

to

/usr/ubuntu-sdk-ide/share/qtcreator/welcomescreen/widgets/IconAndLin
k.qml

Otherwise there is a race in loading the image provider depending on other code. This is expected because the loader is part of the UITK.

The proposed solution is not a bugfix but more a workaround. The /usr/ubuntu-sdk-ide/share/qtcreator/welcomescreen/widgets/IconAndLink.qml is a upstream source file and should not need to import UITK.

Can we somehow get the same behaviour in a different way?

[Cris Dywan (kalikiana)]

I assumed you were using the scaling image provider intentionally. if you're not, there must be a chance Image.source extension is loaded due to an import elsewhere without the image loader being in place - maybe ucqquickimageextension.cpp should check http://doc.qt.io/qt-5/qqmlengine.html#imageProvider before using it?

Adding ubuntu-ui-toolkit to the affected packages.
This should be fixed in the toolkit ultimately because mixing different QML toolkits will be common
at least on desktop (using Qt Controls)
