Actual experiementation shows me that both are needed! you need --login 
on the first bash so that /etc/profile gets executed. The -c then 
executes putting you in the right directory. The "; exec bash" is needed 
so that the -c command doesn't complete. If it did then bash would exit 
and you'd just have a flicker on the screen. In this new exec'ed bash 
there has been no indication to bash that you want any start up scripts 
to be processed. Putting --login on the second exec'ed bash gets you 
back to the same problem since /etc/profile does a cd "$HOME". Yet 
without any startup scripts running your enviornment is less than ideal. 
So you need -rcfile ~/.bash_login on the second, exec'ed bash so run 
your rcfile.

To recap, for bare bones Windows window execution you need:

bash --login -c "cd '%1'; exec bash -rcfile ~/.bash_login"

For an rxvt window do:

rxvt -e bash --login -c "cd '%1'; exec bash -rcfile ~/.bash_login"
