            Bug ID: 354647
           Summary: kio slaves die for all KDE4 applications using Plasma
                    5 (15.08.2) and KF 5.15.0 on migrated profiles
           Product: kio
           Version: unspecified
          Platform: Gentoo Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: faure@kde.org
          Reporter: till2.schaefer@uni-dortmund.de

Whenever i use an KDE4 Application (such as Kile, Krusader, Ksnapshot, etc)
inside Plasma 5 (Version 15.08.2, KF 5.15) i get an error message such as: 

"The process for the file protocol died unexpectedly" 

This is related to kio slaves dying. For example i have attached the log output
of kile below. It is not limited to the file kio slave, but it also happens
with other kio slaves such as ftp (tested inside krusader). 

The bug is limited to users (tested two different ones), that already had KDE4
installed and therefore a ~/.kde4 folder with all the kde4 settings existed. If
i create a fresh user, this bug is not present. Therefore i tried to remove all
~/.kde4/share/config/kio* files, but with no luck. 

If you advise me, which config files might also be related, i will test this
systematically, such that we can track down the problematic source.
