Unfortunately upstream won't be merging the third patch to 5.6 series, so it's only in Qt 5.8. It hides the problem instead of fixing the problem, which is that there is a plugin that doesn't unregister its objects before unloading.
I've prepared another silo https://bileto.ubuntu.com/#/ticket/2015 with alternative third patch that _is_ being considered for 5.6: https://codereview.qt-project.org/#/c/172173/ Let's test it and if it fixes the problem too, land that one instead. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtbase-opensource-src in Ubuntu. https://bugs.launchpad.net/bugs/1618590 Title: scoperunner crashed with SIGSEGV in QObject::disconnect() Status in Canonical System Image: Confirmed Status in qtbase-opensource-src package in Ubuntu: In Progress Status in unity-scope-click package in Ubuntu: Invalid Bug description: crash ProblemType: Crash DistroRelease: Ubuntu 16.10 Package: unity-scope-click 0.1.1+16.10.20160808-0ubuntu1 ProcVersionSignature: Ubuntu 4.4.0-9136.55-generic 4.4.16 Uname: Linux 4.4.0-9136-generic x86_64 ApportVersion: 2.20.3-0ubuntu7 Architecture: amd64 Date: Tue Aug 30 17:54:20 2016 ExecutablePath: /usr/lib/x86_64-linux-gnu/unity-scopes/scoperunner InstallationDate: Installed on 2016-08-27 (3 days ago) InstallationMedia: Ubuntu 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) ProcCmdline: /usr/lib/x86_64-linux-gnu/unity-scopes/scoperunner /usr/lib/x86_64-linux-gnu/unity-scopes/clickapps/clickscope.ini Scope: Apps Signal: 11 SourcePackage: unity-scope-click StacktraceTop: QObject::disconnect(QObject const*, char const*, QObject const*, char const*) () from /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 ??
