--- Comment #4 from Aaron Williams <aar...@doofus.org> --- I deleted the search_db folder and that appears to have solved it. My guess is something in it caused the internal data structures used by KMail to become corrupted and crash. I was at my wit's end with this and resorted to copy/pasting email addresses. Hopefully, this doesn't return. -- You are receiving this mail because: You are the assignee for the bug.
