Application that crashed: dolphin
Version of the application: 1.3
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.3
Operating System: Linux 2.6.31-gentoo-r6 x86_64

What I was doing when the application crashed:
Dolphin shows many things in the network:/ kioslave when accessing my own computer.

Among these are the computer itself (which also leads to a crash when clicked on, but this is another bug) and three pulseaudio-related things: a sink, a source and something which seems to be the pulseaudio server. Clicking on any of these causes dolphin to crash.

Using KDE 4.3.3 on Gentoo.

 -- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
The current source language is "auto; currently asm".
