is there a bug in ZfD6.5 SP2 similar to TiD 10096774?

We have the Problem that Workstations goes into an loop when using
scripted Image. Imaging Save Data is written correct:

Justed Imaged=True
Scripted Image Flag=True
Script Checksum=xxxxxxxxx

After succesfull running the Script and typing again "imaging.s", or
reboot the Workstation, Imaging begins again... and again, and again :(.

ScriptedImage Objekt is associated by the Serverpolicy via MAC Adress.
This all worked just fine befor upgrading to SP2. No changes were made.
C1 Snapins are correct.
