Divide by zero error in queuer progress

Queuer crashes with a divide by zero error when working queuing lots of proxies. Looks like the discrete progress (total task progress) reaches completion well before all proxies have finished.

self.completed_tasks must be decrementing faster than it should be for some reason? May be the task handler is running multiple times for the same messages? Better check the checksums are working properly.
