"java.lang.arithmeticexception divide by zero" dictionary problem

Hi everyone,
I have this problem with my dictionaries on M96. I have a number of stardict dictionaries, that all worked well until I updated the device.
Since then, every time I select a word to make the dictionary give me a translation, it returns me instead the sentence "java.lang.arithmeticexception divide by zero".
What does i mean? How can I solve?
Thanks to everyone will kindly help! :D
