touch browser crashes when invoking contextual menu in landscape orientation

[unerds]

copy text works fine in portrait, crashes in landscape..

to reproduce exactly, was looking up how to sync my google calendar on https://help.ubuntu.com/community/SyncEvolution

tried to copy one of the text boxes containing terminal commands - crashes every time in landscape mode

TEST CASE
1. Launch the web browser and open the amazon.com
2. Rotate the device to landscape orientation
3. Tap on the screen and hold your finger for a while

ACTUAL RESULT
Observe that webbrowser-app disappeared (closed or crashed)

EXPECTED RESULT
No Crash

---

1 - OS version 15.04 r111 (has been occurring over several updates though)
1a- installed on nexus 4 via multirom

2 - webbrowser-app version 0.23+15.04.20150217.1-0ubuntu1

3 - i expected to get the selected text copied to the clipboard so i could paste it into the terminal

4 - browser shut down and i was returned to the apps launcher

I can reliably reproduce the issue. Here is the backtrace of the crash:

The same happens when invoking the contextual menu in any other orientation than the default, portrait one (including inverted portrait).

An issue that might be related: if I browse to a page that displays a javascript alert dialog, and then rotate the device, the dialog is rotated, but its background isn’t resized.

This seems to be an issue in the UITK, I can reproduce with the following sample scene:

import QtQuick 2.0
import Ubuntu.Components 1.1
import Ubuntu.Components.Popups 1.0

OrientationHelper {
    MouseArea {
        anchors.fill: parent
        onClicked: {
            PopupUtils.open(popover)
        }
        Component {
            id: popover
            ActionSelectionPopover {
                actions: Action { text: "test" }
            }
        }
    }
}

Status changed to 'Confirmed' because the bug affects multiple users.

[Cris Dywan (kalikiana)]

Unfortunately this proves difficult to debug as QtCreator can't handle crashes well and Autopilot is still unable to run tests in Landscape https://code.launchpad.net/~canonical/unity8/fake_platform_sensors_module/+merge/247334

[Cris Dywan (kalikiana)]

Small update: I've found a way to simulate orientation in a way that can be used for manual and automated testing.

[Pietro Albini (pietroalbini)]

This bug doesn't appear anymore with the unity8 shell rotation, in the latest OTA.

[TenLeftFingers (tenleftfingers)]

Since OTA-5, this has not happened on my BQ E4.5.

[Olivier Tilloy (osomon)]

I confirm that this has been fixed with the shell rotation in unity8.
