The package includes file(s) larger than 20 KiB in FILESDIR. Please move them to SRC_URI (or remove). "files/ffdiaporama-2.1-libav10.patch" exceeds 20k in size; 24.2 KiB total (proxy-maint can host the file for you if necessary)
I cant' make it fit under 20k and have no way to host it to move it to SRC_URI. I suggest considering updating ffdiaporama according to the bug I submitted some months ago (bug #613230). I managed to reduce file sizes for this version.
