I get bitten by this bug every once in a while, too. When the crash happens, it's \
usually when I've been rapidly deleting a bunch of characters. Most of the files I \
edit in Kate are Python files, but I'm not sure whether that's related to the above \
case or just a coincidence.

How to reproduce (sometimes):

1. Open a medium-to-large Python file.
2. Go to the beginning of a line in the middle of the file, and hit the "Delete" \
button. 3. Hit the down arrow.
4. Repeat steps 2 and 3 repeatedly and very quickly (i.e., delete, down, delete, \
down, delete, down). Kate crashes.

For what it's worth, here's my backtrace:
