Bug 321426

Application: akregator (4.10.4)
KDE Platform Version: 4.10.4 (Compiled from sources)
Qt Version: 4.8.4
Operating System: Linux 3.9.4 x86_64

-- Information about the crash:
- What I was doing when the application crashed:
	Just started, nothing else.
- Reproducible at least 5/5.

- NixOS specifics: we (can) have many versions installed at once on strange (hashed) paths. This can cause problems with apps saving the paths of binaries into settings. However, this was run with consistent KDE-4.10.4 on PATH.

The crash can be reproduced every time.

-- Backtrace:
Application: Akregator (akregator), signal: Segmentation fault
Using host libthread_db library "/nix/store/zm4bhsm8lprkzvrjgqr0klfkvr21als4-glibc-2.17/lib/libthread_db.so.1".
