Description Michal Sylwester 2014-01-21 01:25:36 UTC
Running maintenance -> image quality sorter leaks memory.
When running on my collection it leaked few MB/sec up to around 7G (around 6-7% of my collection according to progress bar) when I stopped it. Had to exit digikam to release it.

Reproducible: Always

Steps to Reproduce:
1. Run Maintenance -> Image Quality Sorter

Actual Results:  
Memory usage grows around few MB/sec
It is not released until exiting digikam 

Expected Results:  
Memory usage stays flat, any extra memory allocated during quality sorting is released after this process ends.
