The sessions are saved as python commands in the .dpy file. If you
open that file, you will see all the DANCE commands that are necessary
to reconstruct your scene. In addition, each .dpy file has a
corresponding subdirectory where it stores all the helper files that
are needed (geometry files, etc.). If your session file is named
mysession.dpy, then the subdirectory is named: dancesession. mysession.

To figure out why the session file is causing the crash, I would open
the .dpy file, and start commenting out the python commands, starting
from the end until you find out which particular command is causing
the problem. There might be something obvious in the file itself
(corrupted data or bad formatiing).

If you want, you can email me the .dpy file (or just post it to this
newsgroup) and I will examine it for you.
