[webkit-dev] webkit gtk memory leaks with PNG/JPEG images

Dear All, We are working on webkitGtk( ( with gtk-directfb backend ) and ported for MIPS platform. We observed there are memory leaks with PNG/JPG image rendering. I am using webkit-1.2.0 version and i set cache model to * WEBKIT_CACHE_MODEL_DOCUMENT_VIEWER*. When I am rendering the 1.3MB PNG image it is consuming around 7MB memory but after deletion I observed that around 1.3MB memory leak. I enabled cache dumpstats but there is no images cached. could you please suggest me is there any patch to avoid image related memory leaks with webkitGtk. Please help me on this. Please find the attached sample html which i am using Thanks In Advance.
