Steps to reproduce: Include an entry like this in your org-capture-templates: ("t" "Todo" entry (file+headline "~/org/gtd.org" "Tasks") "* TODO %?\n %i\n %a")
Now, delete everything in ~/org/gtd.org except for a lone "Tasks" headline. Put point on the next line, and start a capture with the template above. Move point down to the beginning of the line with the "Tasks" link, and C-k (org-kill-line). For me, emacs crashes with "Fatal error (6)Aborted". If I first modify the link and undo the changes, there is no crash. Can anyone else reproduce?
