--- Comment #1 from Emmanuel Pescosta <emmanuelpescosta099@gmail.com> ---
Thanks for the bug report, I can reproduce the problem!

After some debugging and digging around in KIO DropJob, I am 100% sure that the
bug is in Qt (see https://bugreports.qt.io/browse/QTBUG-894). 

KIO DropJob uses the proposed drop action only when modifier keys were set
(because Qt defaults to copy when no modifiers were present), if no modifiers
were set KIO DropJob will ask the user. With this Qt Bug the modifier keys are
always empty (= NoModifier) and so KIO always opens the popup, even when the
right drop action was proposed by Qt.


I have added some debug output to KItemListController::dropEvent:

* Drop with shift pressed:
org.kde.dolphin: KItemListController::dropEvent
QFlags<Qt::KeyboardModifiers>(NoModifier) Qt::DropAction(Movion)

* Drop with ctrl pressed:
org.kde.dolphin: KItemListController::dropEvent
QFlags<Qt::KeyboardModifiers>(NoModifier) Qt::DropAction(Copion)

* Drop without a modifier key:
org.kde.dolphin: KItemListController::dropEvent
QFlags<Qt::KeyboardModifiers>(NoModifier) Qt::DropAction(Copion)
