Application: kded4 ($Id$)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.5.0-2.fc17.x86_64 x86_64
Distribution: "Fedora release 17 (Beefy Miracle)"

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

I was logging in to KDE

- Unusual behavior I noticed:
My dock was missing and right-clicking the desktop background did nothing.  I discovered plasma-desktop was not running.  When I looked in my .xsession-errors I found:

/usr/bin/plasma-desktop: symbol lookup error: /usr/lib64/kde4/plasma_applet_networkmanagement.so: undefined symbol: _ZN5Solid7Control18NetworkManagerNm0914compareVersionERK7QString
plasma-desktop(1286): Communication problem with  "plasma-desktop" , it probably crashed. 

I also noted in my /var/log/yum.log:
Aug 09 12:14:33 Updated: 1:kde-plasma-networkmanagement-0.9.0.4-1.fc17.x86_64
Aug 09 12:14:34 Updated: 1:kde-plasma-networkmanagement-libs-0.9.0.4-1.fc17.x86_64

so I suspect the two are connected.
