No need to. It's a bug and I've reproduced it.

The conditions to trigger it require setting the basic.qos prefetch 
count multiple times on the same channel, while there are active 
consumers. That is quite an unusual setup; more commonly the prefetch 
count is only set once, before consumers are created.

To the OP: you may want to look into that; basic.qos calls are 
synchronous and expensive, so applications should only issue them when 
the prefetch_count settings need changing.
