This test was introduced in pull request #2577. The author of the pull
request included the test, which was originally in #2230, at the same
time as fixing a separate (but related) bug. However, the author did not
include a fix for this test, so when #2577 was merged, a failing test
was introduced.

So I am removing the failing test for now. If anyone wants to fix the
bug, please do so and submit a complete pull request with a test and
a fix.
