Affects: evince (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
When evince is set to dual page view and non-continuous viewing (in view
menu, "Dual" checked, "Continuous" unchecked, pgdn/up must be pressed
twice in order to proceed. This appears to be because the first press of
pgdn increments the current page number, but that page (because of dual
mode) is already displayed. Pressing a second time increments the page
number to a page that is not on the screen, and so advances the view.
