Sorry I don't understand well what you meant, below the current
behavior:

c:\mysql\bin>mysql -uroot
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 1 to server version: 5.0.5-beta-debug

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> use test;
Database changed
mysql> CREATE USER TestUser;
Query OK, 0 rows affected (0.06 sec)

mysql> DROP TABLE mysql.procs_priv;
Query OK, 0 rows affected (0.06 sec)

mysql> DROP USER TestUser;
ERROR 1146 (42S02): Table 'mysql.procs_priv' doesn't exist

MySQL is not interessed to fix this bug.

I had this problem but was able to fix it by running mysql_upgrade.

With mysql  Ver 14.12 Distrib 5.0.26 I found you can work around this as follows

mysql> use mysql;

mysql> create table procs_priv ( test int );
Query OK, 0 rows affected (0.07 sec)

mysql> drop user 'nick'@'localhost';
Query OK, 0 rows affected (0.00 sec)

mysql> drop table procs_priv;
Query OK, 0 rows affected (0.00 sec)

If you encounter this after an update, run mysql_upgrade_shell command: it will create the missing table.

I faced this problem when i was upgrading from mysql 4.0 to mysql 5.1. I resolved this by running, 'mysql_fix_privilege_tables'.
