Test failure: test encoder::compression::deflate::tests::test_deflate

When building image-tiff (vesion 0.7.2), I get the following error:

Does this happen on master / 0.7.3 as well?

[emixa-d]

It also happens on 0.7.3.

Some additional information: rust-flate2 is (locally) being compiled with the "zlib" feature, to use the zlib library that is installed anyway instead of adding a bunch of new dependencies; maybe that's relevant?
