This time I just opened an existing file in kate (my .bashrc). I was able to 
view it and resize the window, but when I started moving the cursor down the 
page with 'down-arrow' it locked up about 10 lines down. I don't think this 
backtrace adds anything, but it's short. The one thing that sticks out to me 
is the 'needWrap' variable. It may be nothing, but that seems to be common to 
the crashes:

     needWrap=0xbfe297f8, endX=0xbfe297ec)

   The same undefined symbol output continues in konsole:

   IIRC, Tim, you said the undefined symbol stuff is normal?
