Hard crashes with DataGrid loading data from VServer

Do I need to handle data from VServer differently from Valentina local? The reason I'm asking is because I'm getting hard crashes when loading data from VServer instead of Valentina local.

For Valentina local everything works nicely for Cocoa. When I change this to VServer I get crashes as soon as data is loaded. The crash log is below. The code is quite simple:

Sub RequestRowData(RowNumber as Integer,Row as DataGridRow)
  
  'add rows in the listbox: into cells for non-id fields, into a rowtag Dictionary for id fields
  
  dim theCol as integer = 1
  dim FieldCount as Integer = DataCursor.FieldCount
  dim RowIDInformation as new Dictionary
  DataCursor.Position = RowNumber
  
  For currentField as Integer = 1 to FieldCount
    
    If left(DataCursor.Field(currentField).Name, 6) = "order_" then
      'ignore, is just for sorting because Valentina doesn't sort case IN-sensitive on Lion anymore
    Elseif InStr(DataCursor.Field(currentField).Name, "ID") = 0 then
      Row.CellText(theCol) = DataCursor.Field(currentField).GetString
      theCol = theCol + 1
    else
      RowIDInformation.Value(DataCursor.Field(currentField).Name) = DataCursor.Field(currentField).GetString
    end if
  next
  Row.ItemData = RowIDInformation
  
End Sub

Between row 14 and 18 the crash occurs. When I change the row

      Row.CellText(theCol) = DataCursor.Field(currentField).GetString

to 

      Row.CellText(theCol) = "test"

then there is no crash! Do I have a senior moment? Or am I simply doing something wrong?

Using Real.Studio 2011R4, latest plugins for DataGrid and Valentina. 10.7.2, Cocoa!
