While playing around with osmosis (V0.39) I got this error when trying to select a way in JOSM from the new generated OSM-file:

map.osm I got from the export-tab on ​http://www.openstreetmap.org/ (no error when selecting ways)

Starting osmosis with this comman-line

osmosis-latest\osmosis-0.39\bin\osmosis.bat --read-xml enableDateParsing=no file=map.osm --bounding-box top=-1.379 left=30.06761 bottom=-1.38604 right=30.07448 --way-key-value keyValueList="boundary.administrative" --used-node --write-xml file=map1.osm

I created map1.osm. When I try to select a way from this data I get the errormessage in JOSM.

I've attached both OSM-Files
