Bug 487530

SUMMARY
After scanning a few pages, when exporting a PDF, there is no indication of the export progress. The dialog 

For small PDFs this may not be a problem, but for large PDFs with OCR enabled, the export process may take some time (especially with OCR).  However, the app doesn't show any indication that saving is still in progress. The only way I can tell that the PDF is still being exported is my CPU goes high for several seconds and I only know that it's done when it goes back down.

STEPS TO REPRODUCE
1. Scan a few pages with text
2. Export the PDF but make sure you have OCR enabled
3. Press the save button

OBSERVED RESULT
The dialog disappears. There is no way for you to know if it's still saving or if it's done

EXPECTED RESULT
A dialog, or some inidication should show that the app is still not done saving the file.
