Another exec loop \o/. 
I think it needs the standard QPointer guard.

This technically needs to be moved to libkonq (of which Folder has a copy, and which is the party spawning those message boxes), however it doesn't have a product and the konqueror product doesn't have a component for the lib.

Adding dfaure ...

Doesn't happen for *all* dialogs either, e.g. the "your paste is about to overwrite a file with itself" dialog is fine. So it needs an audit of all the cases in libkonq.

Comment 4 Louis Moureaux 2014-12-21 13:08:25 UTC

Doesn't affect me with plasmashell 5.1.2 and Qt 5.4.

Comment 5 Marco Martin 2016-02-24 13:45:11 UTC

does it still happen?

Comment 6 Marco Martin 2016-11-07 16:36:56 UTC

closing after didn't seem to happen to anybody anymore after several months was asked for reproducibility
