beryl-manager crashes on startup

[smokey74]

Binary package hint: beryl-core

When I startup beryl-manager in feisty fawn beta nothing happens most of the time. And when it does start only my active desktop is visible.
Furthermore the buttonbar on the tp of every active window disapears. btw. I am running the 64 bit version of Kubuntu

Thanks for taking the time to report this bug and helping to make Ubuntu better. However, this beryl package is not from the official Ubuntu repositories, and as such is not supported here. Please report this bug upstream at http://bugs.beryl-project.org/ . Thanks!
