So, after investigating this bug a bit, I was able to reproduce it locally (thanks to https://wiki.ubuntu.com/ProposedMigration#I.27m_seeing_a_squid_proxy.3F__My_tests_behave_differently_there.21), and was also able to confirm that when $http_proxy is unset, everything passes.
My first attempt at a real fix for this problem was to edit the two test functions (TestSRV and TestTraceInfoOnTimeout, both from request_test.go), and add the following snippet at the top of each one: os.Unsetenv("http_proxy") For some very strange reason, this doesn't work. It should, but it doesn't. I still can't believe it... Anyway, the next best solution was to override dh_auto_test and unset $http_proxy there (thanks, Lucas), given that dh_golang_autopkgtest will invoke it anyway. This works. I'm attaching the debdiff that fixes the problem.
