[Box-Admins] Seems like I broke source.squeak.org's email sending

[Levente Uzonyi]

Hi All,

I uploaded System-ul.721, which has a class comment with some formatting 
in it, and I suspect that the image can't create a diff for that. It seems 
like it broke the email sending, because I got no email for that commit, 
nor for any further commits.
If you feel like you know how to quickly fix this, then please do. 
Otherwise I'll have to find the instructions to access the image. :)
