Link to profile at this site not always working..

Hi there,

Some times there is an error in linking or lockup of the user profile from posts..

In this case I tried to open twix0815 user profile to see who hi is, but got a 'Page not found' with a random user profile..

Usually the link to the users profile is like '{profilename}/public/', but for twix0815 the profile name in the link is his email account (i guess).. and not working..
