SYS.UET$ mutating table

I'm getting a ORA-06512 error on a trigger that for each insert into Table A inserts a record into Table B. The message text tells me that it is a mutating table error. The odd thing about it is that it says that its on table SYS.UET$. Can anyone tell me what this system table is and why it may be mutating because of a trigger that hasn't been changed in 6 months. Thanks for your help.
