It works for me. If I run an xterm -- that is launched from the GUI that
is my desktop -- my umask works. If I run Firefox, and have it save a
file, it works.

I forgot to say that my .bash_profile has this in it, so just about
everything sees the .bashrc:

$ cat .bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
	. ~/.bashrc
fi

etc.
