error when retrieving HopObj by accessname on programmatic collection

getting HopObjects by accessname does not work for programmatic collections
created with getCollection().

i tried the minimal case HopObject.getCollection({"accessname":
"ALIAS"}).get("validalias") and more complex ones, all fail with "Error
retrieving Node" - see strace attached.

also note that a normal collection fails silently (and returns null) when no
object with the requested accessname exists

probably related:

this throws NPE when trying to load the one story with an accessname, all other
stories before and after that are loaded correctly:
{{{
var coll = Story.getCollection( {"alias": "STO_ALIAS"} );
coll.list(0,10);
}}}
