Bug description:
  Evince crashes when clicking on the blank document area during the
  short interval between Evince's window opening, and before the
  document has been loaded.

  Steps to reproduce:
  1. Find a PDF file (the larger the better, so that there's a greater time window)
  2. Double click it to open the document in Evince.
  3. When Evince's window appears, click on the blank document area immediately. This has to be done before the document loads in the window.
  4. Observe Evince segfault.

  SegvAnalysis:
   Segfault happened at: 0x9c1964 <ev_pixbuf_cache_set_selection_list+436>:	mov    0x58(%eax),%edx
   PC (0x009c1964) ok
   source "0x58(%eax)" (0x00000058) not located in a known VMA region (needed readable region)!
   destination "%edx" ok
  SegvReason: reading NULL VMA
  Signal: 11
