The page module is only one example where the method 
t3lib_BEfunc::thumbCode is currently being used. This could be called 
from every backend extension (maybe in future also from FE ones).

It would therefore be fine if this method would return an error code or 
throw an exception in the case, when one file is not found. This would 
help to write better backend extensions. Even other extensions should be 
able to log such events.
