            Bug ID: 319730
           Summary: local contrast crashes digikam when used for second
                    time
    Classification: Unclassified
           Product: digikam
           Version: 3.1.0
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: Image Editor
          Assignee: digikam-devel at kde.org
          Reporter: matthias.mendler at gmail.com

The local contrast filter works fine - for the first time. When I use it on a
second picture, it crashes digikam. 

I can start the local contrast filter and apply it. I can also change the
settings, preview, apply it. As soon as I open it again, as soon as the filter
starts working - doesn't matter wheter applying it or previewing it - it
crashes digikam. It doesn't matter wheter I use it on the same file or another
one, it doesn't matter whether I close the image editor in between or not. 

This happens with the 18 MP pictures from my camera. I have no problem with
smaller pictures (just tried it with a 1280x1024 picture). But also with
smaller pictures: After opening the local contrast filter for the second time,
it slows down.
Now that I tried to reproduce it a few times I also realised, that it works
sometimes. Can't really tell yet when a crash occurs and when not.

Reproducible: Sometimes

Steps to Reproduce:
1. Open an image in image editor
2. Start local contrast filter
3. Apply it (and close local contrast filter)
4. Open local contrast filter agian
5. Apply it again
Actual Results:  
Digikam crashes

Expected Results:  
local contrast filter is applied
