Application: kate (3.10.5)
KDE Platform Version: 4.10.5
Qt Version: 4.8.6
Operating System: Linux 3.11-3.slh.3-aptosid-686 i686
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:
Dragging and dropping some files between two ROX-Filer windows, not even touching KATE, which crashed in the background. The many other times KATE has crashed it has been when scrolling text, copying or pasting text, or typing. I suspect this is all related to my original bug #309784, which got merged into #294241 and then marked as solved on 2013-03-27 by a complete rewrite of folding related stuff, yet the crashes continue. I'm not sure if these fixes have filtered down to my version yet - I'm currently using KATE Version 3.10.5 Using KDE Development Platform 4.10.5 on Debian sid/aptosid running fluxbox. I'm not able to install kate.git master, from kate-editor.org/get-it as suggested as this is a production system. And sorry, I can't provide example text files as they contain personal info, but it seems completely unrelated to content, as this crash shows, and is unrepeatable, seeming just random. I just hope that you can make some sense of the backtrace. I generally have between five and fifteen KATE Sessions running (alongside browser, Terminals, file managers, etc.), each of which has between ten and a hundred documents.

- Custom settings of the application:
I use lots of text files with "Other/Diff" Syntax Highlighting, because I like the colours : )   Maybe I should pick a different Syntax-Highlighting scheme, because KATE crashes often like this.
