[rt-users] Blacklist is not working on 3.6.1

[Roy El-Hames]

Hi ;
The system 3.6.1, apach2,mod_perl 2
I upgraded my production instance from 3.4.4 to rt.3.6.1 over the 
weekend and It seems (in my RT instance anyway) that the Blacklist 
function stopped working??
Must admit thats something I did not test during development??
Anyone else use it and did not work for them but found a fix ??
