I am getting an internal server error when I set a date custom field to nothing.

I have a custom field that is of data type: Date.
I have it filled in with a date (any is fine).
When I attempt to remove the date from the field, I receive an internal server error.
When I attempt to change the date, it works fine.

Anyone else getting this??

Illegal mix of collations with utf vs latin1... but all of my tables are set to utf... so not sure where its going wrong now.
