Spamming space works for me. The problem is if your in a group and the whole group doesn´t spacebar you will still see the jump to lightspeed and will dc.
I'd love to know how you can spam the spacebar and click through the next 3 or 4 dialog choices before the animation begins, without crashing on Esseles. Because once the hyperspace animation starts you will crash, no matter what you do. It can't be displayed on screen, or the error has already happened.
P.S. - I run solo, I never group.
