-- Information about the crash:
- What I was doing when the application crashed:  Normal login.  Also had Verizon USB device plugged in and used KPPP to connect to the Internet. This was followed by KDE Wallet Manager requesting password so that Kopete could sign in to Yahoo IM.  The crash occurred at the same time that KDE Wallet Manager requested the password.

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