Bug 266440

Application: krfb (4.6.00 (4.6.0))
KDE Platform Version: 4.6.00 (4.6.0) (Compiled from sources)
Qt Version: 4.7.1
Operating System: Linux 2.6.37-pf2 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:

I started KRFB (avahi-daemon not running). I started avahi-daemon, KRFB crashed. This isn't isolated to KRFB : I'm trying to port kinetd to KDE4, and starting avahi-daemon while kinetd is listening (and is dnssd publishing!) makes kded crash (same/similar backtrace.not good at reading them)

The crash can be reproduced every time.

-- Backtrace:
Application: Desktop Sharing (krfb), signal: Segmentation fault
