Errors reading qmltypes file generated by the qmlplugindump utility

I am not able to generate working <plugin>.qmltypes files for my plugins.
By 'working' I mean files, that can be successfully loaded in QtCreator for syntax highlighting for my custom types.

The error I am getting says:

Warnings while parsing QML type information of C:/Users/jakubn/Documents/projekty/qt-projects/deploy/plugins/Release/5.12.0/MSVC/x64/IzAuthorization:
Failed to parse "C:/Users/jakubn/Documents/projekty/qt-projects/deploy/plugins/Release/5.12.0/MSVC/x64/IzAuthorization/IzAuthorization.qmltypes".
Error: 17:40: Expected token `;'

In generated files I see that qmlplugindump parses properties of my types as follows:

Property { name: "permissions" type: "QStringList" }

When I manually edit it and add ';' between properties:

Property { name: "permissions"; type: "QStringList" }

file is loading ok in QtC.

I generate .qmltypes with:

'qmlplugindump -nonrelocatable IzAuthorization 1.0 C:/Users/jakubn/Documents/projekty/qt-projects/iz-authorization/../deploy/plugins/Release/5.12.0/MSVC/x64'

using custom CMake script.

I have tried QtC 4.7.3 and 4.8.0-beta1 from maintenance tool - both with same results.
I am using latest Qt 5.12.4 Qt 5.12.0 -- beta4 version of the Qt from maintenance tool in fully updated Windows 7
I am additionaly attaching screenshot of the error from QtC, two variants of the generated files: original and edited by hand and my hacky CMake script to generate them.
