Filter photos with no lens/camera info does nothing
I have several photos with no lens or camera info: scanned files, stripped exif data by programs...
In the "collect images" module, when I select "lens", an empty line represents those fotos, but clicking it does nothing or at least it does not filter that kind of photos. The same for "camera" filter.
I can provide samples if you want.
