Cseries :: Insufficient RAM On Nokia C6 - Cannot Open Photo App

I have the following problem recently occurred on my C6 device. When I try to open Photos app a system error appear telling me that there is not enough memory to open the photos and to close some applications. I have nothing else running on the phone neither active application nor background application. I have over 280 pictures in the memory card, but I do not think that its the problem. I made hard reset but the problem still exist.
