In my profile I have two pictures for my profile, one from Gravatar and one that I uploaded previously. As profile picture I have selected my Gravatar.
Now I have the problem, that my Profile image changes to the uploaded image, when I select "Change picture" -> "Upload a new picture" and then close "Add Image"-PopUp without uploading any image.
I have reproduced this on two different PCs and different browsers. I can even reproduce this on my tablet.
Can anybody confirm this behavior. I'm not sure if this is a bug or a caching problem.
