Bug 276621

Application: kded4 ($Id$)
KDE Platform Version: 4.6.4 (4.6.4)
Qt Version: 4.7.3
Operating System: Linux 2.6.39-2-686-pae i686
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:
Nothing, more or less.  I had just rebooted, and this was the initial login to the system.  My system autostarts emacs, Icedove (=Thunderbird), Iceweasel (=Firefox), and Epiphany (browser).  In addition, the system popped up a dialogue box about ``KDE detected that one or more internal sound devices were removed.'', asking me whether I wanted to forget about them.

   I had just tried to move Epiphany to desktop 3 a couple of time (not realizing I was already _on_ desktop 3) when the Crash Reporting Assistant showed up.

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Segmentation fault
