 To reproduce:
         Won't produce error:
                 a) Simply open the attributes table window on a ShapeFile
 layer
         Will produce error:
                 a) Change the layer to editable
                 b) Add a new point
                 c) Open the attributes table

 The memory usage will then increase about about 1G (in my test example).
 Of course this then causes the system to run slowly if you don't have that
 much memory!

 This seems very similar to #1198, however there is no PostGIS involved.
 Are they related?

 I notice there are two memory leak fixes that involved PostGIS NULL
 values, but again, this doesn't involve PostGIS.  [8217], [6391]
