mysql_insert() first opens all affected tables (which implicitly starts a transaction in InnoDB), then stat tables. A failure to open a stat table caused open_tables() to abort the current stmt transaction (trans_rollback_stmt()). So, from the server point of view the following ha_write_row()-s happened outside of a transactions, and the server didn't bother to commit them. The server has a mechanism to prevent a transaction being unexpectedly committed or rolled back in the middle of a statement - if an operation takes place _in a sub-statement_ it cannot change the transaction state. Operations on stat tables are exactly that - they are not allowed to change a transaction state. Put them in a sub-statement to make sure they don't.
