           Summary: crash after rebuild all thumbnails
           Product: digikam
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: unspecified
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: Julien at narboux.fr


Version:           svn 12/09/2009 (using KDE 4.2.4)
Installed from:    Compiled From Sources

I encountered a first bug : 
1- I edited a picture in digikam and converted the picture in grayscale.
2- I saved the picture as another name
In digikam, the thumbnail of the original picture was changed into a grayscale
picture althoug it should be in color as i didn't change the orginal I just
used save as. The original picture was ok only the thumbnail had been damaged.
I decided to update thumbnail using f5 , it did not change anything, the
thumbnail was still not in par with the pictures.
Then I decided to use the rebuild all thumbnails command, scanning only for
missing thumbnails.
Digikam crashed at the end. I saw the thumbnail flickering in the background of
the "rebuild all thumbnails" window just before the crash.
