Hi,
Since I upgraded from Ubuntu 16.10 to 17.04, my Guest portal for my UniFi system was broken (https://www.ubnt.com/download/unifi/).
Curl gave me the following response:
# curl -vvvv --compress localhost:8880/guest/s/default/
* Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 8880 (#0)
> GET /guest/s/default/ HTTP/1.1
> Host: localhost:8880
> User-Agent: curl/7.52.1
> Accept: */*
> Accept-Encoding: deflate, gzip
>

* Error while processing content unencoding: invalid code lengths set
* Failed writing data
* Curl_http_done: called premature == 1
* Closing connection 0
curl: (23) Error while processing content unencoding: invalid code lengths set
After some debugging, I found out that downgrading to zlib 1:1.2.8.dfsg-2ubuntu5.1 was a workaround.
Now after digging into the issue some more, I found the following upstream patch (unreleased version), fixes the issue:
https://github.com/madler/zlib/commit/f9694097dd69354b03cb8af959094c7f260db0a1
I've created a new package, and its working fine again.
Now as the UniFi controller is just some Tomcat, which relies on Java (OpenJDK), which uses zlib for its built-in Compression/Decompression. I guess even more java related tools can be broken. But I didn't have time to test this.
At least some other people using UniFi have the same issue, see:

[Test Case]
Just install a fresh Ubuntu 17.04 with UniFi controller. And the Guest Portal is broken. See above.
When disabling compression in curl, it works fine.

[Regression Potential]
Everybody upgrading from 16.10 (or previous) to 17.04 will be affected by this.
The patch is taken from upstream, so this isn't a change we will need to keep different from upstream.
I've already created a new package (see debdiff) that fixes the issue.

[Test Case]
- Install UniFi controller on Ubuntu 17.04 (http://dl.ubnt.com/unifi/5.4.16/unifi_sysvinit_all.deb)
- Go to https://<ip>:8443/manage/site/default/settings/guestcontrol
- Or do: curl -vvvv --compress <ip>:8880/guest/s/default/
When compression is enabled, its broken.
