[kepler-dev] error dragging a relation from a port

I have checked in a fix that may solve this problem.
However, I'm unable to reproduce the scenario that originally
triggered my previous, imperfect, fix.  So please, if you see
any anomalies, and most especially if you can reproduce them,
please let me know.

I suspect there is still a threading bug somewhere, where
either something is getting done outside the Swing event thread
that should be done in that thread, or there is some other
thread interaction...

I hate threads :-(
