Admin app error when removing a plugin file

[Alan Etkin]

I updated web2py from mercurial repository. This is a very small issue, not sure if open a ticket for this.

An error ticket is created after removing a plugin view file with the admin app.

Traceback (most recent call last):
 File "/home/spametki/web2py/web2py-hg/gluon/restricted.py", line 205, in restricted

Should be fixed in trunk

I updated my local web2py hg repo, but the problem persists.

Solved it although by changing an admin view function parameter. Attached is the view diff
