Bug In Node Browser Beta30

When I open the node browser in b30, it is empty of items, if I click the main section, where the nodes should be I get an exception (attached)
If I click one of the filter buttons, all is good nodes appear in the list and I can select them.
Never use the browser, so only found this by accident!
