If you receive an email dated enough in the future, for example in the  
year 2155, imp 6.2.22's Mailbox::Ui::getDate() function returns  
invalid data, which makes the JSON contain an email with Date property  
set to false instead of a date, which makes the whole imp to break  
entirely. No folder list, no email list, nothing. The user cannot fix  
this without deleting the email through some other application.

It can easily be patched by adding a check for what strftime returns  
and if it's false then return _("Unknown Date") instead of what  
strftime says.
