Bug Description

image 202

1. Take a picture from the camera
2. Open the gallery app and tap on the new image's thumbnail

What happens:
The image does not open, rather a black screen is shown.

Note: this issue only appears in gallery-app and does not show in photoroll of the camera. Also the thumbnails of photos show just fine in gallery as well.

Confirming:

However this only seems to effect photos taken from the rear camera, front facing and videos (from the rear camera) are showing up correctly in gallery

This is caused by a recent change in the thumbnailer, which fails now to return large preview images.
https://code.launchpad.net/~jpakkane/thumbnailer/memfixes/+merge/245550

The previous code has a code path for generating full resolution thumbnails, but due to a bug (that was corrected in the branch above) that code path was never hit.

The branch above makes that code path accessible again, but it triggers another bug: the images are actually returned by the thumbnailer image provider not into the requested size but in the full resolution, which the GPU can not handle, so they appear black.

This patch will fix the issue by providing proper scaling:

However a quicker and more correct fix would be to simply not go through the thumbnailer to get the image, as the camera photo roll already does. the linked branch implements such a fix.
