Bug ID: 44296
           Summary: Qt 5 programs fail to resolve DNS SRV records
           Product: Wine
           Version: 1.8.5
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: dnsapi

ZIP file containing reproducible test case.

One of our test cases from Mumble [1] tests our SRV resolving code.

The test passes on Windows 10 (all I've tested), but fails on Wine (wine-1.8.5
(Ubuntu 1.8.5-1ubuntu2)).

On Wine, the test fails due to Qt's QDnsLookup failing with
QDnsLookup::ServerFailureError.

The code in Qt 5 is here:
https://github.com/qt/qtbase/blob/19b0ce5daa31e2ffebfcf2701143742302f1deb4/s...

So it seems like a call to DnsQuery_W for resolving SRV records is failing with
DNS_ERROR_RCODE_SERVER_FAILURE.

I've not dug deeper yet, I just wanted to file this upstream early.
