[lazarus] tmaskedit access violation on close

[Ken Moffat]

I receive this error when closing Lazarus with a project open that 
contains 2 maskedits linked to 2 up/down controls. Everything else 
deletes fine, this is the only error. (It shows a message box; the below 
error message is from the xterm I ran lazarus from)

TCustomFormEditor.DeleteControl TMASKEDIT FALSE
TComponentInterface.Delete ERROR: "Maskedit1:TMASKEDIT" Access violation
