Crash when cloning

[Beatrix Willius]

It's so quiet here and there is still no beta, but I have a nice  
issue related to my bug of segment faults.

There is one user with the segment faults. Cloning the database  
doesn't work for him, because he can't open the database. So I made a  
nice little function for him, which opens the database and clones it,  
without doing the usual database changes.

Unfortunately, the app crashes when he is doing this. The code and  
the crash log are below:

   'select a database for cloning
   dim theDialog as new OpenDialog
   theDialog.Title = "Please select an Archive to clone..."
   theDialog.Filter = FileTypes.DB
   theFolderitem = theDialog.showModal
   if theFolderitem = nil then Return

   'do a dialog for the clone
   dim CloneFolderitem as FolderItem = saveClone
   if CloneFolderitem = Nil then Return

   'open the database
   theDatabase = new VDatabase
   theDatabase.open(theFolderitem)

   'now clone the database
   theDatabase.Clone CloneFolderitem, true
   CloneFolderitem.MacCreator = "WebX"
   CloneFolderitem.MacType = "Vdsc"
   theDatabase.Close

   if CloneFolderitem.lastErrorCode <> 0 and  
CloneFolderitem.lastErrorCode <> 101 then
     Globals.theErrorLog.DialogErrorProceed "There was an Error  
writing the Database Clone to Disk! Error: " + str 
(CloneFolderitem.lastErrorCode) + ". Please try again."
   end if
