-- Information about the crash:
I switched on the computer and logged in.  Kwallet asked me for my password to connect to my WiFi connection.  I didn't connect, but I minimized KWallet.  After completion, I shut down my computer.  Later, I switched on my computer again.  KWallet automatically opened at login.  I minimized it again and worked on my computer.  After an hour, I supplied my password.  This crash happened.  Though, WiFi does connect and I can continue working as normal.
