RC7 errors..?

[Angel Vera]

Hi Guys, 

I am using Roller 4.0 RC7.. and when I delete comments I get an error the 
scenario is:
1) Select a comment to delete
2) submit the form
3) it returns you back to the same page, with an error at the top of the page 
saying that there was a error 
4) the comment does get deleted.. anyhow..
