Seems as a bug in the DataFolder's node, there is no FileObject in the node's Lookup.
I've added more logging (type of node), jet-main 29134623d8d8.

Integrated into 'main-golden', will be available in build *201203150400* on (upload may still be in progress)

Comment 7 Tomas Zezula 2012-03-26 11:54:42 UTC
Now it's obvious. Caused by Please Wait.
Comment 8 Tomas Zezula 2012-03-26 13:32:03 UTC
Thanks Jirko, after nearly 3 hours trying it on different OSs I am able to reproduce it.
Has to be in "reduced tree" as Jesse has written in comment #5 but I've overlooked it.
Comment 9 Tomas Zezula 2012-03-26 14:35:43 UTC
Fixed jet-main b80e2ffe220d
