I once had that problem and it was some bug in the 'gd' php extension, which is used to generate image thumbnails. On version 1.3 final you won't have this problem anymore with files. You may have it with avatars and logos, as I think the extension is still being used for that cases. Were you able to upload an avatar for your user?
