Description husdis 2010-06-09 17:24:17 UTC
Application: kate (3.4.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Kate had been running for a few days stably prior to the crash. I just made a new file and was editing it. I went to delete some text at the end of the file (can't remember whether it was highlighted, or just backspacing) and Kate died as soon as I hit backspace.

Xubuntu 10.04, Xubuntu session

I had the following plugings/addons active:
File system browser
Find in files tool view
XML Validation
Text Snippets
Kate Snippets
Quick Document switcher
Text Filter
Terminal tool view
File Templates
Open Header
Build Plugin
External Tools
Tab Bar
Backtrace Browser
Symbol Viewer
CTags Plugin

Data Tools
