3796	JOSM lockup when loading duplicate data	framm	hansendc	"JOSM (latest - 2328) freezes in the ""preparing data set..."" stage, emitting lots of 

can not split, but too deep: 23 size: 19

messages on the console. This happens when I try to load the following URL:

GET http://api.openstreetmap.org/api/0.6/map?bbox=103.83873242862792,13.368442260419624,103.86928061454346,13.394550303033487

The data in this area is broken, seven identical imports have been made on top of each other. 

PLEASE DO NOT FIX THE DATA, this is being looked after already; it's just that JOSM should handle this gracefully. (Maybe something else is wrong with the data - loading a small section of it does work, just the whole thing doesn't.)

I am attaching a saved version of the above data; the lock-up also happens when opening the file.
