Channel icons not appearing in guide on remote frontend using IPv6 (v0.27-72-gea5af90)

[Anthony Messina <amessina@…>]

I'm having an issue on a remote frontend where no channel icons appear in the guide, either entering Live TV or scheduling a recording. The mythfrontend -v file,gui logs reveal the following group of messages for each channel. I am not sure where the "%5" comes from after the icon file name.

I can confirm that mythconverg does not have "%5" as part of the icon name. I can also confirm that the icons exist in the MYTHCONFDIR (/etc/mythtv/channels) and are accessible by the user running the backend (mythtv). If it makes a difference, I am using the blue-abstract-wide theme.

MythUIHelper:

After closer inspection, I can see that the "port" portion ":6543" is included within the brackets, which is causing the failure.

I've traced back from through MythCoreContext::GetMasterHostPrefix to MythCoreContext::GenMythURL and everything *appears* as though it should work. I cannot figure out why the port is inserted inside of the brackets unless the following in mythtv/libs/libmythbase/mythcorecontext.cpp isn't working ~L676:

#if !defined(QT_NO_IPV6)
    // Basically if it appears to be an IPv6 IP surround the IP with [] 
otherwise don't bother
    if (( addr.protocol() == QAbstractSocket::IPv6Protocol ) || 
(host.contains(":")))
        m_host = "[" + host + "]";
#endif

Can you confirm that your configured Master Server IP does not have the port number attached in mythtv-setup?

[Bill Meek <keemllib@…>]

Responding to Mike Deans request on the -users list, the 'printable version' of mine is:

MasterServerIP = fdf9:a66:2cd8:1::223

And, :223 is truly a part of the IPv6 Unique Local Address not a port.

Unfortunately, the above leads to the following output where the redaced IPv6 address is a gloabl IPv6 address (not a link-local):

I neglected to add that my successful tests were done on v0.28-pre-472-gdce054f. I don't get the empty %[024]s above. FWIW, Qt version: compile: 4.8.4, runtime: 4.8.4. I use ULAs, and haven't tried Link-Local addresses.
