-- Information about the crash:
Dear bugsquashers,

In a kate session with ~40 files (mixed .css, .html, .php, .js, and simply text) I selected a large portion of an .html file's text and hit the "Del" button.  Kate crashed at this moment.  The only thing special that I can think of is that I had clicked the little collapsing triangle to the left of a large chunk of javascript a moment earlier to hide the code from view.

 -- Backtrace:
Application: Kate (kdeinit4), signal: Segmentation fault
