Toad does not display output of table variables when executing a procedure or package (4344466)

Toad does not display the table variable output when a stored procedure or package is executed.

Steps to reproduce this problem:

1) Launch Toad execute the table and insert script from this file: toad table.doc
2) Now create the PKG_TOAD package from these files: PKG_TOAD.pkg, PKG_TOAD.pkgb
3) Load the 'PKG_TOAD' package into the Procedure Editor.
4) Go to 'Set Parameters' and select 'Options'
5) Enable the "Enable DBMS Output before debug session" option for the 'Pkg_Toad.SP_TOAD' procedure.
6) Now execute the package. Toad will retrieve 2 lines:

ROWS_AFFECTED = 10
ORA_ERROR_CODE = 0

7) Now launch SQL Navigator and execute the 'PKG_TOAD' package. SQLNav will retrieve 22 lines:

rows_affected = 10
ora_err_code = 0
out_special_charge_c(1) = BAS
out_special_charge_c(2) = BAS
out_special_charge_c(3) = BAS
out_special_charge_c(4) = ENC
out_special_charge_c(5) = BAS
out_special_charge_c(6) = ENC
out_special_charge_c(7) = BAS
out_special_charge_c(8) = ENC
out_special_charge_c(9) = BAS
out_special_charge_c(10) = ENC
out_freight_charge_a(1) = 741
out_freight_charge_a(2) = 741
out_freight_charge_a(3) = 754
out_freight_charge_a(4) = 44.35
out_freight_charge_a(5) = 2125.8
out_freight_charge_a(6) = 42.52
out_freight_charge_a(7) = 2177.59
out_freight_charge_a(8) = 43.55
out_freight_charge_a(9) = 2274.1
out_freight_charge_a(10) = 45.48

The strange thing is that both Toad and SQL Navigator runs the same anonymous block, but gets different results:

DECLARE
ROWS_AFFECTED BINARY_INTEGER;
ORA_ERR_CODE BINARY_INTEGER;
OUT_SPECIAL_CHARGE_C Pkg_Toad.typ_special_charge_c;
OUT_FREIGHT_CHARGE_A Pkg_Toad.typ_freight_charge_a;

BEGIN
ROWS_AFFECTED := NULL;
ORA_ERR_CODE := NULL;
-- OUT_S
