elisp - emacs hangs on viewing pdf -

when view pdf in emacs in default version(emacs -q), doc-view works perfectly. in customized version of emacs, opening smallest of pdfs hangs emacs. can possible reason this?

edit: used bisection , found linum-mode producing problems. once put off, docs opening correctly without delay whatsoever. there way off linum-mode doc-view mode?

edit: higly unorganised, i'm posting .emacs here.
