Are you using gnome-terminal or are you in a console or what?  In a
console, use M-b (ESC-b).

I was rather confused about COMP_WORDBREAKS, and I now see that it only
applies to Readline's Programmable Completion.  You don't need to change it
for what you want to do.

Man bash shows that C-w is bound by default to unix-word-rubout, which uses
whitespace as the delimiter, not COMP_WORDBREAKS.  You may wish to bind C-w
to unix-filename-rubout instead, or switch to using M-Rubout
(ESC-Backspace).  See man bash.
