DTP Error at Write step

Question

Hi ,
   Could any one of you please explain the reason for the following error while loading a DTP?
<b><i>Dump: ABAP/4 processor: OBJECTS_OBJREF_NOT_ASSIGNED
Exceptions in Substep: Load and Generation (Where Necessary) of Write Program</i></b>
We used to get this error when we do a transport to the 2004 s system. It was a bug in the one of the programs of activation of DTP.
I think SAP has provided a OSS note for that and as a part of SP09 I heard that the above issue has been taken care of!!
In my case, my transports are already in production 4 months back, we applied the OSS note and the SP09 . I never got the above error until yesterday.
To fix this error, I just did a reload and it worked out well.
Could any one of you please help me to analyze the cause of that issue?
Thanks,
Ram

In st22 I see this error msg
Name of runtime error:<b>OBJECTS_OBJREF_NOT_ASSIGNED</b>
Exception:<b>CX_SY_REF_IS_INITIAL</b>
Error analysis:
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not
     caught in
    procedure "SET_DP_IN_PROCESS" "(METHOD)", nor was it propagated by a RAIS
     clause.
    Since the caller of the procedure could not have anticipated that the
    exception would occur, the current program is terminated.
    The reason for the exception is:
    You attempted to use a 'NULL' object reference (points to 'nothing')
    access a component (variable: "ME->P_R_LOG").
    An object reference must point to an object (an instance of a class)
    before it can be used to access components.
    Either the reference was never set or it was set to 'NULL' using the
    CLEAR statement.
