New crash information added by DrKonqi

kate (3.8.5) on KDE Platform 4.8.5 (4.8.5) using Qt 4.8.1

- What I was doing when the application crashed:
On the first crash, I was closing a bracket in a HAML file.
Now it crashes everytime I access the file again and click "Recover".

I copied the swap file and my .kde directory to a safe place.

- Custom settings of the application:
HAML highlighting from https://github.com/ouvrages/haml_kate

swap file that crashes kate when I click "recover"
Comment 4 Dominik Haumann 2012-11-08 11:18:31 UTC 
Can you please follow http://www.kate-editor.org/get-it/ and check, whether you can still reproduce?
Comment 5 Michael Witrant 2012-11-14 15:16:48 UTC 
I installed Kate from git and copied the old swap file, but Kate doesn't ask for recover and deletes the swap file.
