This thread is almost a month old, but I too am getting this problem. Edit: I seem to have found a solution (to my problem at least). When KW Rocketry and Station Science are installed together, it seems to cause this crash. I simply uninstalled KW Rocketry (which turned out to be causing another crash as well). While no one in this thread seems to have KW Rocketry, I thought I should update this post in case anyone else has KW Rocketry.
