Adding new asset to collection in IE shows empty set required info dialog and you can not completed add. May be related to large collection.

This does not seem to happen all the time, but this set of steps seems to re-produce the error (Though some of the steps may not be needed).

IE7 on XP, select edit for this collection: http://dev.curriki.org/xwiki/bin/view/GWT/Editor?xpage=plain&page=Coll_RenStopable.Rons2ndColleciton

then select the last file in the first level (TestWordFile). Now select add and try and add a file, after it uploads the file it presents an empty "Set required Information" dialog, and you are stuck. See screen shot.
