Application: kded4 (4.14.8)
KDE Platform Version: 4.14.8 (Compiled from sources)
Qt Version: 4.8.6
Operating System: Linux 4.0.5-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
- What I was doing when the application crashed:
Waking up my desktop from suspend.
- Unusual behavior I noticed:
The crash reporter window showed up and told me that kded4 had crashed. Right before that, there were several icons in the system tray whose style resembled that of WinXP. I'd never seen them before, and they disappeared when the crash reporter window appeared.
- Custom settings of the application:
My /etc/default/grub is modified. Currently it contains GRUB_GFXMODE=800x600 and GRUB_GFXPAYLOAD_LINUX=text, but I booted up this system with GRUB_GFXPAYLOAD_LINUX=keep (and then I modified the file).

-- Backtrace:
Application: Démon de KDE (kded4), signal: Segmentation fault
