The 0.2 release of Genesis still had some issues with the configuration wizard. Some were of minor annoyance, but one was quite serious, making syncevolution crash on sync. Also, Genesis now provides improved security for new configs by making the config files only owner-readable. So in multi-user environments, other users won't be able to read your account data. I recommend you to update to version 0.2.1, which is now available from the project page. And please look out for remaining bugs and report them!
For those interested in technical details:
The reason for the crasher seems to be ConfigObj, which is used for configuration file manipulation. It omits the final newline that usually is the last character in a file. (As far as I know, POSIX even requires this.) And without this final character, syncevolution crashes when reading the configuration file. The fix is now a very simple workaround, that just adds a newline character to the config files after saving.
