Add some logging in convert_dict

Add some logging in convert_dict.

Currently, there is no way to tell what is failing, it is returning silently. This will output some information regarding what error occurred.

I changed the logging to spit out the word instead of the index, as hbono
discussed on irc, you guys sort so the index would be useless for debugging. 

I have tested this with Korean dictionary and it spotted out the corrupted word.
