 Pick a vector, toggle editing, make a change (like moving a feature) and
 then click "save edits", the vertex markers will disappear.

 If you make this test with the "node tool", for example moving a node, the
 resulting effect is even worst:

 select a line or a polygon with the "node tools", move a vertex and click
 "save edits". The vertex markers will disappear.

 Now move again a vertex: the blue square will move, but the adjacent lines
 will not (at this point you can try save edits but it will be as the
 vertex wasn't moved).

 This happens only the first time you try move a vertex, because if you try
 again the tool will work fine.

 Tested with trunk under both linux and windows.
