No, just that you've told Myth to find channel icons somewhere and they 
aren't there.  In other words, you have a value or values in the icon 
field of the channel table in the database that is *not* the actual 
location of the channel icon for the respective channel(s).  So, either 
"UPDATE channel SET icon = '';" or get some icons or fix the values in 
the database...

While one could argue that there's no need for Myth to take so long to 
figure out they're not there, I would instead argue that on a properly 
configured system (one that doesn't have bad values for the icon field) 
you will never experience the problem.  And, IMHO, this "bug" makes for 
a great way to determine that channel icons are not at the location 
specified in the database--that there's a problem with the settings in 
the database that should be corrected.  So, the "bug" lets the user 
"know"* to fix the problem.

However, if you do decide to make a patch for it, I would suggest that 
the patch should /not/ "cache" the non-existence of the file.  Doing so 
could impede users' efforts to fix their database data (

*Where "know" means the user writes to the list, and someone responds 
with, "Myth can't find the channel icons. Fix your config." ;) (Or, even 
better a more verbose description of how to fix the problem.)
