Created attachment 168297 [details] New crash information added by DrKonqi DrKonqi auto-attaching complete backtrace.
I couldn't reproduce the bug though. Could you provide more precise scenario or a video capture ? May have be taken of by https://invent.kde.org/frameworks/kio/-/commit/341a75c7e42ea8bcea07d0a0c0044a5a4f342e07
Created attachment 168300 [details] Screencast of the reproduction of the bug I don't really know how to describe it more precisely so I've attached a screencast to demonstrate the behavior. Will test the patch later.

Will test the patch later. I don't reproduce it. Do you reproduce it with breeze ? I think I fixed already anyway.

Only rolling release distro will get confronted with this. Those distro updated Qt to 6.7 before devs even started using it and Qt 6.7 introduced some very low-level behavior changes causing crashes (deleteLater() now crash when called with a nullptr object, most likely because of https://code.qt.io/cgit/qt/qtbase.git/commit/src/corelib/kernel/qobject.cpp?h=v6.7.0&id=d50746ef3aec72d339f639395a2291009f186680)
