hi guys, hope someone can help

i went to update sib and recieve an error saying
unable to install sib
conflict with application packages: libqt4-maemo5-network (4.6.1~git20100122-0maemo1)

i then tried uninstalling sib and reinatalling but recieve the same error.

possibly this has something to do with the fact that previously i had kmplayer and worldtv installed but i uninstalled them.

any help would be great!
