Comment 1 David Edmundson 2018-01-29 14:31:35 UTC 
You can fix this by replacing the clearly broken:

    QObject::connect(QCoreApplication::instance(), &QCoreApplication::aboutToQuit, ShellManager::instance(), &QObject::deleteLater);

and reparenting ShellManager to app , but then that gives a crash on X :/
Comment 2 David Edmundson 2019-12-22 11:35:10 UTC 
I believe I fixed this ages ago.

I assume you would have nagged me if this was still an issue. Please reopen if it still is an issue.
