-- Information about the crash:
I pasted mediawiki https://en.wikipedia.org/w/index.php?title=List_of_vegetables&action=edit into a new file and started doing find replace. I chose to replace \|[0-9]+ with XXLFXX\0 using regex and then XXLFXX with \n and then it crashed.

The reporter is unsure if this crash is reproducible.

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