I am able to reliably reproduce this crash (exact same stacktrace) with a branch of mine that implements multiple-window support in webbrowser- app¹. On a phone, when closing one of multiple browser windows by swiping it down from the app spread, the window is close()’d then destroy()’d, and the crash reliably happens then. I’m not seeing it happen on my unity7 desktop. Closing and destroying windows there works as expected.
I tried to isolate by writing a simple standalone reproducer that essentially does the same thing with multiple dynamically instantiated windows, but I’m not seeing the crash there, so there is something really browser app specific at play. ¹ lp:~osomon/webbrowser-app/multiple-windows -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to webbrowser-app in Ubuntu. https://bugs.launchpad.net/bugs/1596524 Title: /usr/bin/webbrowser- app:11:QScopedPointer:qGetPtrHelper:QOpenGLContext::d_func:QOpenGLContext::functions:QSGDefaultLayer::invalidated Status in Canonical System Image: Confirmed Status in webbrowser-app package in Ubuntu: Confirmed Bug description: The Ubuntu Error Tracker has been receiving reports about a problem regarding webbrowser-app. This problem was most recently seen with version 0.23+15.04.20160615-0ubuntu1, the problem page at https://errors.ubuntu.com/problem/f539f8b9ffa3e8856a7bbe3dcc25fcde172b1cec contains more details. started with 0.23+15.04.20160615-0ubuntu1 similar signature than bug 1596523 To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1596524/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
