           Summary: Memory leak in image editor
           Product: digikam
           Version: unspecified
          Platform: SuSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: krienke uni-koblenz de


Version:           0.9.0beta1 (using KDE KDE 3.5.3)
Installed from:    SuSE RPMs
Compiler:          gcc 4.1 as well as 4.0.2 
OS:                Linux

Recently I noticed that it seems that imageeditor in 0.9.0 beta1 has a memory leak. When I look at say 50 photos using imageeditor without editing any of the images, just look at them and run through all of these 50 photos my system looses about 300MB of memory. Since I have only a total of 500MB RAM, swap is beeing used at this time more and more. Digikam is getting noticeably more and more slower when loading the next photo in imageeditor since swapping occurs. The strange thing is, that this memory/swap does not seem to be released when I terminate digikam completely. The amount of used swap space (reported by free) remains the very same even a day later this amount is still marked "used". So far only a reboot helped to reclaim the space. So I guess that there must be a memory leak inside the image editor. I found this effect on my suse10.0 (500MB Ram) as well on a suse10.1 (1GB RAM) system. In the latter case it simply take some more photos to run through until on this system swap space is beeing used forever either.

Thanks
