            Bug ID: 353626
           Summary: Processing of bracketed images fails after the first
                    set is done
           Product: digikam
           Version: 4.2.0
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: digikam-devel at kde.org
          Reporter: mmtsales at gmail.com

When combining bracketed images, only the first operation is completed without
errors. If one tries to combine another set of bracketed images after the first
set is done, several assistants (wizards?) and processing windows are opened
and the file can't be saved at the end or processing.

Reproducible: Always

Steps to Reproduce:
1. Select a set of bracketed images and then Click tools -> Combine bracketed
images (I'm translating from portuguese, menu names may not be exactly these)
2. Click next, next, next, finish on the wizard window
3. Preview and save the combined image
4. Repeat steps 1 and 2 for another set of bracketed images
5. Several processing windows are opened. The more consecutive operations you
try, the more processing windows are opened.
6. Close the spare windows and try to preview and save the combined image in
the remaining one.
7. An error is displayed informing that the file could not be saved. Again, the
more consecutive operations you try, the more error messages are displayed.
Sometimes the file is saved despite the error message(s), sometimes it is not
saved.


Actual Results:  
Multiple processing windows are opened after the wizard is finished and
multiple error messages are displayed when trying to process and save the
combined image. The file may or may not be saved.

Expected Results:  
Only one processing window should be displayed after the wizard is finished. No
error should occur when trying to process the images and the combined image
should be allways saved.

To process other sets of bracketed images, the user must close and restart
Digikam after each set is processed. And Digikam takes a looooooong time to
open.
