Problems with duplicate packages after failed yum update

view story

http://forums.fedoraforum.org – Hello! Today I tried to install an rpm package and couldn't. The GUI package installer suggested to run yum-complete-transaction, so I executed that and got: http://pastebin.com/TMx5TZXw, (like 3k lines), it was a lot of duplicated packages. Code: ** Se ha encontrado 89 problema(s) pre existentes en la base de datos RPM, este es el resultado de 'yum check': 1:NetworkManager- es uin duplicado con 1:NetworkManager- 1:NetworkManager-glib- es uin duplicado con 1:NetworkManager-glib- 1:NetworkManager- (HowTos)
