----------------------------------------------+------------------------
 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.

 {{{

 }}}

 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
 }}}
