Bug 509869

SUMMARY
I have found poor behavior of Wayland when compared to X11 in saving Konsole tab behavior between login sessions.

STEPS TO REPRODUCE
System should be a fresh install that has never run X11.  

Problem with respect to Konsole usage. 
1.  Ensure that System Settings > Session > "On login, launch apps that were open: [*] On last logout" is selected.  
2.  Now start multiple instances of Konsole and force multiple tabs in each Konsole window by using Control-Shift-T.  
3.  Within each tab in Konsole, "cd <different directory of choice>".  
4.  Now logout of Wayland and then login with Wayland.  

OBSERVED RESULT
When I do this I now see only one instance of Konsole regardless of the pre-logout greater than 1 Konsole quantity and that Konsole is not showing any tabs, nor does it show any directory location I had been working in prior to logout.  

EXPECTED RESULT
Multiple instances of Konsole should be observed and each Konsole should contain multiple tabs at directory positions that were previously set.  This is not an issue with X11.
