Bug 319797

Application: kded4 ($Id$)
KDE Platform Version: 4.10.2 (Compiled from sources)
Qt Version: 4.8.4
Operating System: Linux 3.9.0-gentoo x86_64
Distribution: "NAME=Gentoo"

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

I just got a crash handler after unlocking my screen lock. This is a Gentoo build, so addresses will differ from binary distributions, but the source lines should help. The crash report assistant considered this a possible duplicate of bug 268185 (indirectly via some other bug), but that one (and the intermediate one) was about an issue at startup.

The bug mentions a possible alsa-lib issue, which was fixed in alsa-lib in january. I have media-libs/alsa-lib-1.0.27-r2 installed, which I would guess should include fixes from january. I do have strange issues with my sound config on a regular basis: KDE often tells me that a device might have suddenly vanished, and whether it should forget about it. It seems like the device might just be too slow to respond, because I often do head the intended sound, some time after that message appears.

- Custom settings of the application:

Due to my attempts to debug bug #306338 a while ago, I have disabled various kded modules which might be enabled by default. I won't risk opening the system settings just now, for fear that the session with this bug reporter might freeze or crash on me since kded is gone.

-- Backtrace:
