I had a similar thing happen to me a few days ago, I went to a pickup raid with my illu alt and I dropped my settings from the main setup to my raid setup (to avoid HUGE lag) afterI finished I loaded up my main settings. From there each time I did /camp name I crashed!! the way I solved it was to do /load_uisettings and reload the ui from another char,this worked fine for me and I've had no problems since, you could always give that a try and see what happens.
