Please describe the problem:
Create a longish postscript file.  View it in evince and scroll down to a page
further on.

Now overwrite the postscript file with a new, shorter document.  When viewing
this in evince, a collection of CRITICALs appears in the terminal:
** (evince:17524): CRITICAL **: ev_page_cache_get_page_label: assertion `page >=
0 && page < page_cache->n_pages' failed

(evince:17524): Gtk-CRITICAL **: gtk_entry_set_text: assertion `text != NULL' failed

** (evince:17524): CRITICAL **: ev_page_cache_get_size: assertion `page >= 0 &&
page < page_cache->n_pages' failed

** (evince:17524): CRITICAL **: ev_page_cache_get_size: assertion `page >= 0 &&
page < page_cache->n_pages' failed

** (evince:17524): CRITICAL **: ev_page_cache_get_size: assertion `page >= 0 &&
page < page_cache->n_pages' failed

** (evince:17524): CRITICAL **: ev_page_cache_get_size: assertion `page >= 0 &&
page < page_cache->n_pages' failed


Steps to reproduce:
1. Load up the user guide in Yelp.  Select print Document and save it to a
postscript file.
2. View in evince and scroll to any page > 1
3. Restart yelp with the user guide.  Select print page and save it over the
same file.
4. View again in evince

Does this happen every time?


Other information:
Maybe not a big deal but since Critical warning now crash, it gets a little
frustrating
