When Plasma 5.8.3 and kf5-kio-core-5.27.0-1.fc24.x86_64 arrived into
F24, I started experiencing
"the process for file procotol is dead unexpectedly"
error messages when opening file picker in Qt based applications.
I opened bugreport  and then I started trying to retrieve debuginfos.
I installed kdebugsettings, enabled the KIO debug messages, but I don't
see any message related to the crash in both ~/.xsession-errors and
journalctl. I attach
~/.config/QtProject/qtlogging.ini at URL
