You still have the -Xmx512M, I'm going to give you a picture so you know exactly what to do. I know you said you don't have the -Xmx512M in there anymore, but the crash report says you still do. If its not in that box, then I would set up a new profile and try it there, is that doesn't work, then delete minecraft and redownload it (of course taking any neccessary backups first).
