Application: plasma-desktop (4.11.1)
KDE Platform Version: 4.11.1
Qt Version: 4.8.5
Operating System: Linux 3.11.3-201.fc19.x86_64 x86_64
Distribution: "Fedora release 19 (Schrödinger’s Cat)"

-- Information about the crash:
- What I was doing when the application crashed: Tried to run Wine Boot which triggered an SElinux error (mmap_zero access). Then executed (as root) "setsebool wine_mmap_zero_ignore=1". KDE appeared to immediately crash and restart.

- Unusual behavior I noticed: KDE desktop and panel went black, some apps were left running on the virtual desktop (e.g. Konsole). Desktop apparently rebuilt itself.

- Custom settings of the application: Wine had already quit/crashed. SELinux is enabled and enforcing. The only change made subsequent to Wine quit/crash was to run 

"restorecon /usr/bin/wine-preloader" and  "setsebool wine_mmap_zero_ignore=1" as root.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Aborted
