[Steps]
1. Create a Calc doc and a Writer doc.
2. Focus on Calc doc, "Data" -> "DataPilot" -> "Start", select "Data source
registered in OpenOffice.org" on "Select Source" dialog-box, and press OK
button. In the "Select Data Source" dialog-box, choose Bibliography, biblio and
Query in "Database", "Data source" and "Type" respectively, and press OK button.
Then pop-up a prompt: There exist no query named "biblio".
3. Switch to Writer doc, and switch back.

[Result]
1. When switch back to Calc doc, the prompt dialog-box increases one.
2. Repeat step 3 for n times, the prompt dialog-box increases n.
3. Press OK button on each prompt dialog-box, pop-up DataPilot dialog-box. Press
Cancel button on all the DataPilot dialog-boxes, only the last one can be
canceled. The others still display and there's no way to close these
dialog-boxes except close the Calc program.

[Expectation]
prompt dialog-box won't increase when program switchs.
