New Revision: 16208

URL: http://svn.gna.org/viewcvs/relax?rev=16208&view=rev
Log:
Fix for the post_reset() method of the Analysis_controller object.

This unregisters all the analyses from the observer objects, and calls the 
set_init_state() method
only once all analysis pages are deleted.  This in combination with the 
synchronous reset user
function calling prevents the GUI from blowing up!
