Comment 1 for bug 1774739

Note I have tried using the .run offline installer of Qt 5.6/5.9/5.11, what seems to happen is that they work on Ubuntu 16.04, 17.10 but fail on 18.04 - this is the stacktrace for reference https://pastebin.ubuntu.com/p/Yzj5gsmwQ3/

So it seems possible that it might be some underlying change to the platform (maybe something like dbus? or a new config/dir I need to enable).

Furthermore it looks like this issue may affect Qt applications when they try to run as a snap under the core18 snap. https://github.com/snapcore/core18/issues/4
