-- Information about the crash:
Started kate (new window, no existing file)
pasted in 4 long (aprox 1600 chars) lines.
Did following replace
Find:,
Replace:,\n    
(some spaces after the \n)
Mode: Requalr expression.
action Replace All (no current selection).
I then added 4 additional new lines breaking some existing lines into two.
I then changed the replace mode to Plain Text (left Find and Replace unchanged) and clicked Replace All. At this point it crashed.

The crash can be reproduced some of the time.
