Bug also triggers on replays, and can be caused by having the minimap window open for long periods. Build 17 does not suffer the bug after the steps to reproduce.
To reproduce:
Open attached replay in trunk revision 6467 or later (earliest I have available).
Open the minimap.
Increase game speed to 10x, or whatever speed you can use smoothly. On my system at 10x it takes around 20 minutes to trigger the bug.
