It's almost certainly a permissions problem--where the backend and/or 
frontend process was not allowed to access the files (or the directory, 
or one of the parent directories--like the mythtv user's home directory, 
which should only be accessible by the mythtv user).  This could be 
caused by many things, including use of the --user argument to 
mythbackend depending on what user actually starts the process, or what 
user is starting processes, or even the script that's starting processes.

Alternatively, it could be caused by using multiple $HOME/.mythtv 
directories, for example, due to different users running the system or 
because say, your distro created one directory for MythTV configuration 
somewhere on the file system (outside the home directory structure) and 
made a symlink at ~mythtv/.mythtv pointing to that directory, but then 
you copied stuff over from your old system and broke their symlink so 
that only some processes were using your new directory and others used 
the "old"/distro-configured directory or any number of other such breakages.

Meaning, in summary, the channel icons weren't broken, but your system's 
configuration was (and may still be, if you have multiple different 
config directories in use--where "broken" may not involve any problems 
or visible issues at this point).
