I got this recently, except the message was: > /usr/bin/how-can-i-help:244:in `&': no implicit conversion of true into Array > (TypeError)
'true' rather than 'nil'. But on subsequent runs it printed 'nil' like in the bug report (some system state had changed). Athos Ribeiro's proposed patch fixes the 'nil' case; I don't think it would fix the 'true' case.
