[rt-users] dashboard my reminders error after upgrade to RT 4

[Jon Tollerton]

After upgrading to RT 4 from 3.8.10, I'm seeing several errors in the 
dashboard reminders section in the form "Couldn't find Ticket for 
reminder N. Please contact administrator."  Oddly enough, it displays on 
all users' dashboards.  This seems to only affect two or three really 
old entries as we really don't use the reminder functionality.  It's 
certainly possible that some data was corrupted by my mucking about in 
the database or by using RT-Shredder incorrectly before it was merged 
into the mainline, but I'm not sure where to start looking.

Thanks,
-Jon
