I'm guessing the lines are being given start and end point only, which
is not enough to define a zig-zag line.  Thus, when they try to do their
normal things with too few points, it crashes.  It ought to at least
check that it gets what it needs, and take some reasonable action if it
doesn't.  An example diagram would be nice.

The dtd is in the source, and there's some info on the Dia TWiki.

The right-mouse Edit menu has Cut/Copy/Paste text which does this.  It's
not middle button pasting, but it is pasting.  I'm working on a revamp
of the text editing system which would allow proper cut and paste, but
it's no trivial task.
