That's strange, and probably a bug. The plasma integration plugin does not have runtime dependencies on anything that is only available through an active Plasma5 desktop, to my knowledge. At least you shouldn't get a crash in dolphin. If you only get it once it may indicate that something required isn't yet running and is started automatically, but you still shouldn't get a crash. If DrKonqi appears and gives a useable backtrace you could file a bug report for this.

That is without setting QT_QPA_PLATFORMTHEME I presume?
In that case you get Qt's fallback internal implementation of the plasma-integration plugin, though I don't really understand how that can give you real KDE file dialogs.

Presumably, or the forums. Cross your fingers though that this doesn't irk someone who feels that KDE look-and-feel should be exclusive to the Plasma desktop. I know there's at least 1 dev who already told me he planned to take down some comparable backdoor, "just because he could".
