-- Information about the crash:
- What I was doing when the application crashed:
I caused a seg-fault yesterday after several successful drag and drops.  This morning it seg-faulted immediately on the drop.  Not the same tasks.  I did not find the id of the previous crash.  I did not get the assistant to locate any other ids.

-- Backtrace:
