Ok. Thank you for the information. I understand you are on a different operating system. The version I have on windows is 0.97.2. I have found a workaround though. I get a link from the icon and I put it on the screen instead of trying to join 2 activities directly. I can then move the ends of the link to attach them to the activities. In this case I have no crash. Maybe this can help troubleshoot.
