Comment # 1 on bug 1225961 from Fabian Vogt

Reassigning to AppArmor.

Looking at /etc/apparmor.d/plasmashell, it does mention QtWebEngineProcess but
at a debian specific location, so that probably doesn't match and we can rule
that out as cause.

info="no new privs" is interesting: it means that the plasmashell process got
no_new_privs set on it. I guess that might've been triggered by one of the
plugins, maybe also WebEngine. That should by itself not prevent execution, but
apparently with AppArmor it does?
