SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
the essence of the problem is that after caching-copying, during the copying process itself, the file manager crashes.
I have only tried copying with already existing files in the copy location. But I haven't tried with pure copying, although there may be a bug only in this version of events.


STEPS TO REPRODUCE
1. I start copying (there is a caching process from the WebDAV cloud)
2. closing the file manager
3. the copying process begins

OBSERVED RESULT
file manager crashes

EXPECTED RESULT
if there are duplicates, a window with a question about the action should come out.

Comment 9 Ahmad Samir 2022-09-16 16:42:02 UTC 
The backtrace in comment#6 looks slightly different than the one from comment#0, could be two separate issues... the problem is the backtrace from comment#0 is not complete due to missing debug symbols.

I tried reproducing this issue, and it happened 1-2 times, but I failed to make crash again.

This *might* be related: https://invent.kde.org/frameworks/kio/-/merge_requests/977 (it makes sense to parent the widgets to the dialog, not to its parent anyway). The question is, why is this happening only now when this code has been around for ages?

WidgetsAskUserActionHandler: make sure all dialogs are created in the main thread

In Qt, the GUI runs in its own thread and must be accessed from the
main thread. If QWidget is created in a non-main thread, we can use
the QMetaObject::invokeMethod() method to create it in the main thread.
