Subject: bug#21738: 25.0.50; eww freezes/crashes at times
Date: Fri, 23 Oct 2015 17:16:23 -0400

I updated and rebuilt (without imagemagick).
I still get the same problem if I load eww in a 2-window frame, with fci loaded.
eww loads that webpage fine after I do C-x 1.

Backtrace after C-g and debug-on-quit set to t:

window-end(#<window 3 on *Backtrace*> updated)
  #[(w) "\301 !\302 \303\"B\207" [w window-start window-end updated]
4](#<window 3 on *Backtrace*>)
  mapcar(#[(w) "\301 !\302 \303\"B\207" [w window-start window-end
updated] 4] (#<window 3 on *Backtrace*>))
  fci-delete-unneeded()
  fci-redraw-frame()
  set-window-buffer(nil #<buffer  *temp*-411462>)
  shr-render-td-1((td ((class . "Body") (shr-td-cache-natural . 222)
(shr-td-cache-10-nil 217 222 1 (#("Yank." 0 1 (face variable-pitch
shr-indentation nil) 1 5 (face variable-pitch))) 1 nil nil)) "\n
Yank.\n    ") 268 t)
  shr-render-td((td ((class . "Body") (shr-td-cache-natural . 222)
(shr-td-cache-10-nil 217 222 1 (#("Yank." 0 1 (face variable-pitch
shr-indentation nil) 1 5 (face variable-pitch))) 1 nil nil)) "\n
Yank.\n    ") 268 t)
