So, I finally tried to apply the patch. Good news: it works :) great work!

Slightly less good news, I found two issues:

1. Build failed because of missing include dir for libkdcraw  (because of disc issues my system currently uses kdelibs from packages so I installed gwenview and libkdcraw in a different prefix). This is fixed with this change:

diff --git a/CMakeLists.txt b/CMakeLists.txt
index adcd39c..5b13bb8 100644
--- a/CMakeLists.txt
+++ b/CMakeLists.txt
@@ -78,6 +78,7 @@ include_directories(
     ${KDE4_INCLUDES}
     ${EXIV2_INCLUDE_DIR}
     ${NEPOMUK_CORE_INCLUDE_DIR}
+    ${KDCRAW_INCLUDE_DIR}
     )
 
 ## dirs to build

2. The ThumbnailProviderTest::testLoadLocal fails. I haven't investigated, but I think it is a regression with orientation handling of JPEG thumbnails. You can build and run all tests by entering the tests/ build dir and running `make check`.

It uses KDcraw to extract the embedded jpeg preview (most of the raw formats contain it for the purposes of quick viewing the photos on the camera display) so it is fast, implementing was quite easy and theoretically it enables gwenview to support everything dcraw supports (practically we need to test more formats). The patch does not perform demosaicing and I don't think it shall - digikam, darktable or rawtherapee are much more suited for developing the 'digital negatives'.

Nikon (tried D50, D70s, D90, D800 and Coolpix P7000), Canon (tried 7D, 5D Mark3 and 6D) and Pentax (K-X, K30) have the preview full-res, while Sony raw files (A900, A850, A58, Nex 3, Nex 6) have only 1616x1050.
