myCursor = nil -> crash

[jda]

Hi Ruslan,

I just found out that something in the latest 2.0.3 builds crashes 
code that has worked for all previous builds.

I create a temporary database and temporary cursor (meaning, neither 
are written to disk):

   refDB = new myDatabase
   myCursor = new VCursor(refDB, "select * from thereferences where 
false", EVCursorLocation.kServerSide, EVLockType.kReadWrite) //make 
an empty cursor
   if myCursor <> nil then //fill cursor with example values
     myCursor.setBlank
     myCursor = fillMyCursorExample(myCursor)

     ...do stuff...

and when it's finished,

myCursor = nil
refDB = nil

This crashes in myCursor = nil (refDB = nil is OK).

If I remove the line, my app crashes when the function is done (and 
an implicit nil occurs). Here's the crash log:

Any suggestions?
