Question/Problem with MasterPlaceholders missing size/scale information

One of our customers is giving us presentations with a master which contains a placeholder that does not have any size information. It looks fine in Powerpoint, but when we go to clone any slide from the presentation, an exception is thrown.

I've attached a sample demonstrating this. I'm not sure how our customer created such a powerpoint or how pervasive their problem is with their presentation library. Is this something that might be an Aspose bug? Is it something that Aspose just doesn't support? I'm using PPT 2003 SP2.

Any help would be appreciated.
