[Openstreetmap] Problem with tags in server

OK, now I think I have a test case.  The problem was that if a node
was created with empty tags then the following updates seems to fail
sometimes.  I have checked in a test program in the osmpedit directory
in subversion.

phyllis:~/osm/svn/osmpedit> perl test --user username --passwd secret --nodetagupdate
DATA: <osm version='0.2'>
<node lon='15.558601' tags='' lat='58.408306'/>
</osm>

  <node lon='15.558601' tags='' uid='296014' lat='58.408306'/>
</osm>
DATA: <osm version='0.2'>
<node lon='15.558601' tags='name=Tommy1;' uid='296014'  lat='58.408306'/>

</osm>

<node lon='15.558601' tags='name=Tommy2;' uid='296014'  lat='58.408306'/>

UPDATED NODE 2: <osm version='0.2'>
  <node lon='15.558601' tags='name=Tommy2;' uid='296014' lat='58.408306'/>

Node 296014 deleted

----

The tags field in "UPDATED NODE 1" is empty but should be
"name=Tommy1;".  The following call setting it to "name=Tommy2;"
works.

If I create the node with non empty tags value it seems to work robustly.
