lilypond linux does not like b flat !!!!

[Eby Mani]

I'm pulling my hair over this strange thing that has affected stable releases 
of lilypond v2.14.2 from 2.18.2 on Ubuntu 12.04 with gedit and on LilyBin.com

Lilypond does not like "bes" at all and it won't print b flat !!!!. Anyone had 
this problem ?. I don't have any other platform(OSX / Windows) to check.

Thanks,

Eby
