Comment 11 Akseli Lahtinen 2023-11-29 12:38:52 UTC 
Managed to reproduce the bug:

1. In target device, create file named file500
2. Copy a lot of files to the target device, including ones that are not in the target device, say files named file1 to file500
3. Close dolphin while its copying
4. Wait til the last file, file500 is asking to be overwritten
5. Crash happens when the overwrite window cant open

To clarify, the files from 1-499 should not overwrite anything.

The bug happens because something tries to spawn the overwrite window through dolphin, but dolphin window is closed.

WidgetsAskUserActionHandler: Use QPointer to check the validity of parent widgets

If Dolphin is closed during the copying process,
and the overwrite/skip dialog appears,
this crashes the copying process since the 
parent shows to faulty location.

Use QPointer to check that the parent widgets are still
valid. If not, we just use nullptr, and the dialogs
will still open.

This also cleans some repetition in code.

This commit breaks a (kf5) kio rebuild (kf6 kio is fine at 25add040d, which includes the parallel bdef648ed  from a couple weeks ago), at least on a hybrid kf5/kf6 system updating from yesterday  using the gentoo/kde overlay.   Occurs immediately after  [381/472] in the build process.  The errors are below.  (5.239.9999 is gentoo/kde's pseudo-version used for the kf5 frameworks live-git slot.)
