bug#13482: 24.2.50; doc-view initialization fails when opening files with find-file-noselect

[Andreas Politz]

emacs -Q
(find-file-noselect "some.pdf")
(switch-to-buffer "some.pdf")
(doc-view-current-page) => nil

This seems to be a very subtle bug, since Edebugging
`image-mode-winprops' avoids it.

After function doc-view-mode is called, image-mode-winprops-alist looks
fine, but sometime later, around displaying the buffer, something evil
happens to the value of this variable.
