Mitch if this is still happening, report it -- upstream. It seems
clear from your explanation that this is not a packaging bug, so just
go to and report against Konsole. If that is the wrong
component, the devels will move it. This could be a problem in session
management too, and I think but am not sure that is covered by Plasma.
In any case, just put the information you gave us to the KDE devels in
your bug report.

It is best to always report, even if you aren't precisely sure where
it should be. One note: the single-sign-on system for KDE does not yet
cover bko, so if you've never logged in there, you will need to create
a login.


PS: There is no KDE5. Plasma 5, please!
