            Bug ID: 325712
           Summary: Face tagging has massive memory leak
    Classification: Unclassified
           Product: digikam
           Version: unspecified
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Face Management
          Assignee: digikam-devel at kde.org
          Reporter: rene at colorcube.de

When you tag faces digikam eats all available meory in short time.
I'll add a screentshot of a memory graph.

Bug #323253 might be related.
Because of the bug report I deleted recognition.db and all works fine. Also
tagging, but after editing/tagging hundreds of faces the proplem reappear.
recognition.db is 184M big now.


Reproducible: Always

Steps to Reproduce:
1. Go to 'people' view
2. Start tagging faces
3. Doesn't matter if you stop tagging - memory consumption goes on
Actual Results:  
In less than 5 minutes (often in much shorter time) all available memory is
used: 8G Ram + 8G swap.

Expected Results:  
Don't eat all my memory :-)
