Yes, when I recently added new features to implement
create_aped_line_modifier and create_aped_line_profile, 
I neglected to update the model_spectrum interface.

These bugs have been fixed in the newest source code, 
available from:
 ftp://space.mit.edu/pub/cxc/isis/pre_release/isis-1.4.9-13.tar.gz

Alternatively it should be possible to work around this problem
by using a different interface.  See 'create_aped_fun' for
details.

Thanks,
