24363	JOSM cannot load (some of?) its own savings	Gingko	team	"==== What steps will reproduce the problem?
1. Import objects into JOSM.
For example this one (a single node !) loaded using Overpass API :


{{{
[out:json][timeout:25];
// gather results
node(361706);
// print results
out geom;
}}}


2. Save your contents.
File -> Save As … -> Give a name.
(for example : **node361706.osm**)

3. Quit and restart JOSM.

4. Reload your file.
File -> Open … -> Select the file you just saved.

==== What is the expected result?
Reloading the saved contents.

==== What happens instead?
A dialog appears telling (in French language in my case) that the file 'node361706.osm' cannot be read, because the 'version' attribute is missing from the OSM object with ID 361706 (at line 3, column 71), etc.

==== Please provide any additional information below. Attach a screenshot if possible.
The textual contents of the 'node361706.osm' is the following:


{{{
<?xml version='1.0' encoding='UTF-8'?>
<osm version='0.6' generator='JOSM'>
  <node id='361706' visible='true' lat='48.8308507' lon='2.3562364' />
</osm>
}}}


Effectively, there is no ""version"" attribute into this node contents (whereas it exists in some other files).
I think that JOSM should either take care of writing a version attribute everywhere it is required, or not flag this as an error.

I made a screenshot.
