Bug#744237: dreamchess: During gameplay only, the mouse positions don't sync.

[Lucio Crusca]

Package: dreamchess
Version: 0.2.0-3
Followup-For: Bug #744237

In my case it even segfaults when you click on the chessboard.
I can reproduce this way:

1. start a new game
2. click once the chessboard
3. click one more time
4. segmentation fault

I've built a debug package and took a stack trace:

$ gdb dreamchess

Do you need "set solib-search-path" or "set sysroot"?
