As it states in the Submitting Bugs instructions:
Submitting a Feature Request

Before submitting a feature request here, please make sure:

fill the subject as a sum up of your description
    fill the description as detailed as you can, don't hesitate to describe precisely how this feature should behave, try to add what benefits you're excepting from it
    please DON'T fill the target version field: let the developers decide when integrate
    please DON'T assign the feature request to anybody, let the developers deal with it

I think it would make a lot of sense to be able to set permissions for all fields under the description box except for file upload. Having these fields enabled for a user that is trying to simply submit a bug report is very confusing.
