SecurityException in Identicon Handler in Medium Trust

After upgrading to 2.5.2, I've been getting several errors like this in the log:

System.MethodAccessException:

ttingsSection) ---> System.Security.SecurityException: Request failed. at

The URL being accessed at the time is the IdenticonHandler. Here are two 
examples:

As the exception is code access security related, I'm gathering this is another 
medium trust issue.
