The file does include some more detail:

2010/11/10 09:59:06 WARNUNG (MultiPolygonRelation): 12000022.osm.gz: 
Multipolygon http://www.openstreetmap.org/browse/relation/1239779 
contains errors.
2010/11/10 09:59:06 WARNUNG (MultiPolygonRelation): 12000022.osm.gz: 
Polygon 4611686018427680884(436P)(23072094[436P]) carries role inner but 
is not inside any other polygon. Potentially it does not belong to this 
multipolygon.

The generated polygon mentioned in the detail message has apparently 
been produced from http://www.openstreetmap.org/browse/way/23072094.  
This polygon is between 25.24875 and 25.44025 degrees longitude. Part of 
it is within your bounding box.

Please try to extract this way from your tile file and see if the part 
that is within the bounding box makes sense. Or, to reduce the size of 
the file, first extract only this multipolygon from the input that you 
are feeding to splitter, and then split it. Then you should be able to 
load the tile in JOSM, possibly after some XML header tweaking.
