[Bug 48936] Re: GDM: Greeter application crashing

[MatthewRhodes]

I have the same problem every login. I dont know if this helps but I
have noticed when I change login style to 'Plain' the error message
mentioned appeares, but I get the themed login screen, and when I choose
themed style, it gives the error message but loads Gnome Desktop
Manager.
