Bug 253962

Application: kate (3.4.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-25-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
Kate crashed when filtering text through an external command (sort).
I selected a few tens of lines, choose to filter selected text through an external command (from the Tools menu), wrote "sort" as command name, and applied. Kate immediately crashed.

The crash can be reproduced every time.

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