Bug 283952

Version:           2.3.2
OS:                Linux

The Knights program 2.3.2 and also the git master branch:

If an illegal move is made as the first move by a human the program will crash.  Touching a piece with no moves possible (bishop, king, queen, rook) or an opponents piece with a drag-and-drop mouse action will crash the program before the move is completed.

It occurs only on the first move.  All other times after this the program successfully ignores the illegal move attempt.

It occurs with or without markers activated.

Reproducible: Always

Steps to Reproduce:
1) start Knights in human vs human or human vs chess engine mode.

2) Attempt to drag the white king.

3) System crash before mouse moves significant distance (must be activating the drag-drop event; appears to be immediately after mouse has moved the startDragDistance).

Actual Results:  
crash

Expected Results:  
ignore move attempt

Any click event on a piece will stop the crash if a subsequent illegal move is attempted still on the first human move.

Drag and return to starting point a legal piece (pawn) then attempt an illegal move will also prevent the crash.

It occurs only on an immediate, first mouse move after startup.
