-- Information about the crash:
I was typing a find and replace regular expression with about 170 lines of text selected to search in. 

Dynamic word wrap was off and there were a dozen very long lines at the top of the file (some > 3,000 characters).

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
