[rolfen]

Launching gksudo or gksu will kill rootston.

Can you dump the stack trace?

[rolfen]

How do I do that, please?

[rolfen]

Can anyone else reproduce it?

[chebykinn]

Yes, it fails after closing polkit popup.

wl_list_remove(&view->link) is called on empty link.
I suppose this means that it is called twice on the same link. Is it related to #650?
