When I open a file from folder with lot of images and "Open entire folder at startup" option is on, ristretto show me only the image just selected. Previous and Next button are disabled, title bar show [1/1]. If I close the image, then all the other images on that folder are shown, title bar become [x/total_images]. After I move back or forth, title bar become [new_x/total_images - 1]. Step to reproduce: 1_ "Open entire folder at startup" must be selected; 2_ Go to a folder with more than one image; 3_ Open one image with ristretto; 4_ Only that image are shown, can't move on other images; 5_ Close image; 6_ Other images in the folder are now available, previous image is not available; ArchLinux with XFCE 4.8, ristretto 0.0.93. Dev version from git has the same issue for me.
Fixed in git master: fcb707b507b2a37cb41db93a85a95c78a5b6d3ff
