Title:
Crash when opening QtQuick Controls ComboBox
Status in qtmir package in Ubuntu:
Triaged
Status in unity8 package in Ubuntu:
Triaged
Bug description:
Although QtQuick Controls aren't installed by default on the device
they may be packaged with click applications (such as GCompris).
Currently the ComboBox component from QtQuick Controls exposes a crash
in unity8.
Steps to reproduce:
1) Install qml-module-qtquick-controls
2) Run the following QML:
import QtQuick 2.2
import QtQuick.Controls 1.2
ApplicationWindow {
ComboBox {
}
}
3) Tap the combo box
Expected output:
ComboBox should open
Actual output:
Unity switches back to the dash and then crashes with a segmentation
fault (the application itself continues running)
Backtrace:
Program terminated with signal SIGSEGV, Segmentation fault.
