Bug #911 [ruby-core:20723]; This bug, and occasional ArgumentError in Resolv#resolv, was caused by a resolution timeout.
The timeout would raise an Resolv::ResolvTimeout exception. Following the chain of ancestors backwards from there, one would arrive at Interrupt, which descended from Signal.  Signal#initialize required an argument, and Interrupt's own #initialize likewise did so, but should not. The fix was to backport r12226 from the 1.8.7 branch, which fixes Interrupt#initialize. Fixing that clears this bug.
