profile values erased when calling user profile form programatically with specific category

This module fit the requirements for my current project, however I needed to add a form in block for a specifc category. After saving the values ALL profile fields where erased. The issue was that on the update case of the hook_user it expects to not come an argument for a category the URL (as arg(3)), this does not happen when you load the user profile form programatically, instead it should check if the category is not the default (i.e. account). I've fixed this in my local code and provided a patch so it can be applied. I haven't done much testing but it has worked for me so far :).
