are you sure the ppa version installed properly?
$ apt-show-versions xenner
xenner 0.41-1ubuntu5.1~sevenmachines1
i can reproduce the problem with xenner 0.41-1ubuntu5 from karmic main on a vanilla karmic install, and xenner 0.41-1ubuntu5.1~sevenmachines1 works as it should with no errors. so if you're using the same package i'm not sure whats going wrong.
