Please provide any additional information below.

I select the commit in the repo, but no diff tab displayed.

If I upload manually instead, appears perfectly.
This is what the log is telling me:

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe1 in position 4872: ordinal not in range(128)

What can I do? I don't see the problem. 

And it is a curious behavior, because in the beginning was working.

The installation of ReviewBoard has around 2 months and in the beginning was working fine.
Thanks
