user_constraints ORA-01013: user requested cancel of current operation

Hello,

I'm retrieving data from user_constraints view and I get ORA-01013: user requested cancel of current operation 

I've updated stats for following tables - these are included in user_constraints view defintion

EXEC DBMS_STATS.GATHER_TABLE_STATS('SYS', 'CON$');

EXEC DBMS_STATS.GATHER_TABLE_STATS('SYS', 'CDEF$');

EXEC DBMS_STATS.GATHER_TABLE_STATS('SYS', 'USER_EDITIONING$');

EXEC DBMS_STATS.GATHER_TABLE_STATS('SYS', 'COL$');

EXEC DBMS_STATS.GATHER_TABLE_STATS('SYS', 'COLTYPE$');

EXEC DBMS_STATS.GATHER_TABLE_STATS('SYS', 'OBJ$');

EXEC DBMS_STATS.GATHER_TABLE_STATS('SYS', 'USER$');

But still query of the view user_constraints or "SYS"."INT$INT$DBA_CONSTRAINTS" is broken by ORA-01013
