Unfortunately the backtrace is lacking debug symbols. If you are able to reproduce please install debug packages and attach a new backtrace.

Actually, I should have recognized the symptoms of a classic Video Card failure.  Erratic colors, screen locking, and applications which demand more from the card crashing.  Kwin (and associated applications) tend to crash on me when my Video Card gets weak.  And now I have black screen, but can boot into the terminal.  

Long story short, you can close this.  The issue is hardware, not KDE.
