Witch Crash when using support gem on Demon Form

Bug Report ID: #1124058978

I learned Demon Form and was using support gems lvl 1. Made a Vitality gem for Deamon form since it said seemed like it was a choice. After i closed the skill panel i started a fps crashing till i removed the skill Demon From and doing so it removed the support gems and all was fine. When relearning the skill again i went to manually put in the support gems and the Vitality gem won't go in.

So conclusion my crashing was from the auto equip of the creation of the Vitality support gem into Deamon Form was the cause.
