Its not rom bug, you have leftovers on your SD, you need to delete all files inside DCIM folder except your pictures it self, meaning all thumbnials or other none picture files and than it will work, faced this my self each time switching roms...
it's not a bug ! it has to do something with DCIM folder , delete the folder and try again...( in the dcim folder are the pictures so better back up) and try after that
Thanks guys! Flashed viperS 5.0 and deleted thumbnails folder and now photo editor is working.
