... and apparently you already tested against your hypothesis and detected 
it to be flawed, too? For sending files to Mac users I would expect 
https://bugzilla.gnome.org/show_bug.cgi?id=682566 as the most probable 
cause. But Windows and Linux users should not have that problem.

We take backward and forward compatibility very serious during development. 
So even an older version of Dia shall be able to read files created by a 
newer version.

If the creating Dia version has more shapes available than the receiving 
version there will be a message like:
 "Unknown types while reading diagram file
  Presentation - Sozi Frame"
and editing unknown shapes can not be edited. Some manual shape exchange 
should be able to fix this.

If there a the newer Dia version has some object properties unknown to the 
older version these proeprties will be silently ignored.

HTH,
