Bug 233224

Application: kate (3.4.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.31-20-generic x86_64
Distribution: Ubuntu 9.10

-- Information about the crash:
I had some C code pasted into a Python file to copy it. I saved and tried to run it before realizing I hadn't deleted the C code. I went back to the file selected the C code with the mouse, hit backspace, and Kate was gone.

The file is not at all large, but I had been running some pretty cpu and memory heavy stuff from the terminal within Kate before this happened.

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