Description
The following code segfault when it updates the text property of the TextArea. But it only happens when text is initialised first with qsTr (translations are not defined).
function set_document(document) {
title_text_area.text = document.title // -> segfault
}
TextArea {
id: title_text_area
// text: 'Title ...' // ok
text: qsTr('Title ...') // -> segault
}
Backtrace
Thread 1 "python" received signal SIGSEGV, Segmentation fault.
