i hate to be the first , but ..
steps to reproduce:
1. create a new character
2. press the new (faction) button
3. press the appearence tab
4. click on faction color
5. click on summary tab
The color palette stays in foreground, after clicking on cancel or ok or somewhere else game hangs and then crashes.
I tried this and crashed 3 times, so you could also check if you got the report sent 3 times.
