I could be wrong, but I am pretty sure you are not allowed to issue
commits - or rollbacks - in a trigger. That rules out not only the
commits of your inserts, but especially your "execute immediate

Wolfgang, you're never wrong. If it appears that you are wrong, it must
be the work of Satan. In this case, however,
I can strenghten tour belief with an excerpt from 9i Application
developers guide:
Restrictions on Creating Triggers
Coding triggers requires some restrictions that are not required for
standard PL/SQL blocks. The following sections discuss these restrictions.
Maximum Trigger Size
The size of a trigger cannot be more than 32K.
SQL Statements Allowed in Trigger Bodies
The body of a trigger can contain DML SQL statements. It can also
contain |SELECT| statements, but they must be |SELECT|... |INTO|...
statements or the |SELECT| statement in the definition of a cursor.
DDL statements are not allowed in the body of a trigger. Also, no
transaction control statements are allowed in a trigger. |ROLLBACK|,
|COMMIT|, and |SAVEPOINT| cannot be used.For system triggers,
{|CREATE|/|ALTER|/|DROP|} |TABLE| statements and |ALTER|...|COMPILE| are
allowed.
