Created attachment 1012938 [details] Screenshot System update failed a couple of times. Now, after reboot I get a popup that is too large for the screen and that cannot be closed.
I don't know what program specifically is giving you this error, but it's certainly got nothing to do with anaconda-yum-plugins. That package is dead now, I think.
I know, but I also don't know the application. Would be nice to have a point 'don't know the application' :-)
Fixed upstream in https://git.gnome.org/browse/gnome-software/commit/?h=gnome-3-14&id=1462c9b860f201a943a672408504c1111a369331
