           Summary: colour automatic correction doesn't work if an image
                    was opened in editor for a longer time
           Product: digikam
           Version: 2.0.0
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Image Editor
        AssignedTo: digikam-devel at kde.org
        ReportedBy: linux at drmartinus.de


Version:           2.0.0 (using KDE 4.6.2) 
OS:                Linux

I've observed this several times now, so I think it's a bug. I open the image
in the image editor and do some other work. After a few minutes (maybe 5), I
want to use the "colour/auto correction" (don't know the exact English name,
since I use the German version, there it is "Farbe/Automatische Korrektur"),
but it won't work. The progress bar is shown, but sits at 0%. I can cancel the
job, but it won't change if I start it again. Other editing operations seem
possible, as fas as I can see.

Reproducible: Didn't try

Steps to Reproduce:
Open an image in the image editor
wait for a few minutes
choose "colour" from the menu
choose the first item, something like "automatic correction"


Actual Results:  
the progress bar in the lower left corner sits at 0%, nothing happens.

Expected Results:  
The correction should proceed, so the progress bar also should show the
progress of the operation.

I only tried this with jpg images. I have no idea if this happens also with
other image types.
