Comment (by jdemeyer):

 Replying to [comment:47 SimonKing]:
 > Until recently, pickling of an object in the Singular interface resulted
 in a pickle that couldn't be unpickled, and my spkg could cope with it. By
 a recent change that I authored, pickling an object in the Singular
 interface works more likely, BUT fails with an error if it is not defined
 in the current base ring. So, now I get an error, where previously I just
 had a partial pickle.

 I'm afraid I can't help you there...
