I found this:

1.) "save session" is already set as default option

2.) When you start kate the first time with an empty or no config directory at 
all. As Michele said kate starts with a "hard-wired" default session.

3.) It does not work like I said before in 2) (see above). When I simply change 
the interface to not show docs list and close kate, it does not get saved. The 
created config/sessions directory stays empty just like Leslie experienced. 
No "default.katesession" file there. I think this is a bug. Users would expect 
a changed default session to be saved in user config dir.

As a workaround you can make kate save a default.katesession file. When you 
open "Default Session" after you started kate first time etc. then it _will_ be 
saved as default.katesession file with the applied changes.

Otherwise, when the file ~/.trinity/share/apps/kate/sessions/default.katesession 
already exists there seems to be no problem.

That happens when there is still no file
~/.trinity/share/apps/kate/sessions/default.katesession

ACK
