Bug 341270

- What I was doing when the application crashed:
Ran KDevelop with `kdevelop 2>&1 | fgrep waka` and it seems the pipe is problem. I was debugging a plugin so I wanted to grep.

When I run `kdevelop 2>&1` or without `2>&1` I get no crash.

This does not affect usability of KDevelop. The last session window still loads fine.

The crash can be reproduced every time.

Reproducible: Always

Steps to Reproduce:
1. Run KDevelop with a pipe: `kdevelop | grep QFile`

Actual Results:  
At least one item internally crashes and brings up Dr Konqi.

Expected Results:  
No crashes.

Qt Version: 4.8.5
Operating System: Linux 3.16.5-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"
