Okey, so what you do in printer-manager is completely unrelated to 

What I am interested in is, how we can use your knowledge to avoid the 
mistake in the kauth design for frameworks.

If I understand mentioned bug correctly, it is not possible to fix the 
crash with the current design of kauth/polkit interaction, because the 
polkit frameworks expects the password dialog to run in its own 

If GNOME still uses polkit, how did they solve the out-of-process 
password dialogs?

Hm, kdeadmin is not moved to git yet, but I guess it still would be 
possible to create a "KDE Admin" project group.
