Well thanks for insisting. Indeed this is a valid use case but in this point I want to check another thing: is this a Qt bug or a KDE one? For what I read on the web everyone seems to complain about KDE apps in non- Plasma desktops. What happens with pure Qt5 apps? Maybe the real "default" should be in KDE apps.

QT5 should really say something when expected > essential environment variables not set... *Maybe* the problem is KDE apps assuming something which is not always true. But if pure Qt 5 apps also show this behavior I'll raise the problem in upstream's mailing list to get it discussed first (I think filing a bug would simply get it closed). So let's first try to rule out if it's a Qt or KDE assumption the one we are fighting now.

Right, we do as much as possible to avoid non upstream-ACKed patches, except in very precise Debian-only cases.

Please check if this also applies to pure Qt5 apps (maybe using upstream's examples might be enough).
