Right -- what I'd like to see is the [hostname] run: /bin/bash -l -c
"..." stuff that should have been printed out by Fabric just before it
actually gives you the above error :)

It *should* look like /bin/bash -l -c "workon mymy && ls", but I
wanted to make sure.

That looks just like what I have (other than using 'source' instead of
'.', but they are equivalent). I'm guessing your bashrc is not
executing fully (i.e. one of the commands in the middle is silently
failing)? Try sticking those commands farther up in the bashrc, or
stick some echo statements throughout to see where it stops executing
so you know what to fix.

Good luck,
Jeff
