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

I performed an apt-get upgrade and then rebooted.  Immediately after login, I was presented with a segfault.  It may be unrelated, but after the update I am no longer able to see wifi networks in range.

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