Binary package hint: aptdaemon

ubuntu: 11.04 (natty)
aptdaemon: 0.41+bzr646-0ubuntu2 (aptdaemon)
I try to install packages and i get an error saying:
an unhandled error occured
there seems to be a programming error in aptdaemon. this is the software that allows you to install/remove software and to perform other package management related tasks.
