possibly bug with somevalue when creating new items

[egonw]

Hi Magnus, in a custom Wikibase I was trying to create new items with a property value somevalue. It works when I do this in two separate steps like

qid,P1,Len
,Q1,"some label"

followed by

qid,P8
Qxxx,somevalue

But when I do:

qid,Len,P8
,"some label",somevalue

the statements error out with a message that somevalue is not known.
