Hi poor guy,a few day ago I faced the same PB, and the solutions seem's the Funniest one
Just open BonusTools.txt in Module directory then change the "+ bonusTools 7.0 /usr/aw/maya7.0/BonusTools" B form Uppercase to Lowercase b like "+ bonusTools 7.0 /usr/aw/maya7.0/bonusTools"
then restart Maya,It will brings the menu well, I think It's will worked for you and help for you,notice
after you exit maya,look the Module directory again,you will find a new bonusTools.txt~ file there
I dont exactty know what maya do,but the PB is solved.
