DDD 3.3 (i686-pc-linux-gnu) gets `BadWindow' error

[Mark]

I was attempting to open "gnuplot" to plot a variable. When gnuplot
didn't launch correctly, I pressed the "Cancel" button in the "Now
launching..." message window, and DDD crashed.

Attached is the ~/.ddd/log file, as requested by the closing DDD
message.
