[Zope-DB] Problems with DCOracle2 and Zope2.7.1

[Piotr Kral]

	Hi
We have a problem with DCOracle2 in our application after upgrading from 
Zope-2.6.0 to 2.7.1. The problem is with Exceptions. When i call a 
python script like this:
########
try:
    x = container.Blade_proc( 1 ) #Blade proc is a stored procedure
    print x
except Exception, err:
    print err

return printed
#########

  on Zope2.6.0 everything is fine, but on Zope2.7.1 I get error, and I'm 
logged out off ZMI, even if I run it as a manager and I get this error:
######
Site Error

An error was encountered while publishing this resource.

Error Type: Unauthorized
Error Value: The container has no security assertions. Access to 1 of 
(dco2.DatabaseError instance at 0xb003164c) denied.

Error log says this:

I think that it's some thing with security policy in Zope2.7.1, but for 
now I haven't got a clue what to do with this. There is a solution to 
convert err to string, but that would take two or three weeks because in 
our application there is a lot of stored procedures ..
I'd be grateful for  any help.
