I assume that you are using ZODB3.  The tree tag (and possibly other
things) try to use persistent object ids for generating HTML.  This
worked in ZODB 2 (aka BobpPOS) but not in ZODB 3, because ZODB 3
uses string object ids that contain binary data, like Nulls.  I've checked
in a fix for this for the tree tag.  This fix will be in 2.0 alpha 3, 
which I plan to release tonight.
