qbot goes into endless loop on Death Canyon

[Zsolt Dollenstein]

When playing on Death Canyon - Invasion Force, qbot suddenly went into an endless loop, rendering the game effectively frozen and pinning one CPU to 100%.

Philip did some investigation on irc:

[22:26:30] <@Philip`> quantumstate: qbot is looping infinitely, with a pattern of function entries like
[22:26:35] <@Philip`> (resources.js:25)
[22:26:38] <@Philip`> (resources.js:43)
[22:26:39] <@Philip`> repeating forever
[22:26:42] <@Philip`> (queue.js:15)
[22:26:44] <@Philip`> (plan-building.js:46)
[22:26:47] <@Philip`> (queue-manager.js:127)

I have attached my commands.txt which reproduces the problem 100% of the time.

I could reproduce it with r11401 (as noted in the irc log).

With these calls it should be the while loop in queue-manager.js:248 that is running forever. Dumping some values shows the problem of a ratio being NaN and the ratioMin staying infinite, never removing the last entry from ratio.

This issue was already fixed in r11684.
