Description:
In a Calc file, I made a dialog and inserted a "Form List Box" in it. In the Data tab page for that control, I set the "Source Cell range" field to Sheet1.A1:A3. After, I changed the name of Sheet1 to SheetX. The "Source Cell range" field automatically changed to SheetX.A1:A3. Perfect! But when I tryed to save the document, the saving procedure aborts, leaving a temporary file lu*.tmp and showing this message: "Error saving the document <filename>. General Error. General input/output error".
When I rename again the sheet to "Sheet1", the save become possible.
Repeating the test with a new document, renaming the sheet *before* creating the dialog, it save. Obviously, renaming again, it do not save.
The bug also can happen with other controls that permits, in a Data tab page, to set some sheet address. In the steps to reproduce, I show the problem with the "Form Spin Button". Nevertheless, the "Form Check Box" seems immune to the bug.


Steps to Reproduce:
1. Create a new Calc document
2. Click the menu Tools > Macros > Organize Dialogs...
3. In the list on the left, click the temporary name of the new document
4. Click the "New..." button 
5. Click the "Ok" button to confirm the name of the new dialog
6. Click the name "Standard" immediately above the dialog name, then click the dialog name: the Edit button become enabled.
7. Click the Edit button: a draft of the new dialog become visibile
8. The Toolbox toolbar should be visible: else put a check on the menu View > Toolbars > Toolbox.
9. On the Toolbox click the Form Spin Button icon.
10. Put the mouse cursor over the dialog draft, then drag it diagonally. A control will be created and selected.
11. On the property pane (to the left) click the Data tab.
12. Read the name of the first sheet in the document. In the next steps you must replace the name Sheet1 with it.
13. In the "Linked cell..." field write Sheet1.A1
14. In the document, rename the Sheet1 spreadsheet with a new name.
15. Try to save the document.


Actual Results:
The document is not saved and the error message do not tell why. A new lu*.tmp file is added.


Expected Results:
The document is saved. No file *.tmp remains
