set -o vi in .bash_profile

[Hans Vansweevelt]

When 'set -o vi' is added in a .bash_profile, this does not seems to
work. However, if I remove it from the .bash_profile and type it manually
after login in, it works. 
Also, when it is in the .bash_profile then vi is on when you do a set -o,
but it does not work, even if you enter the command manually.
So the only way for me to have vi-editing is to leave it out of the
profile and enter it after login in.
This happens with bash 1.14.7 and bash2 2.03.
Can someone tell me how I can add it in some profile so that it doesn't
have to be typed in every login-session ?
