Thanks Eli.

eww works fine without Imagemagick.
But then I lose all the emacs features that need Imagemagick (like
formula image rendering in org-> latex exports).

Does the backtrace give a hint to what could have gone wrong with the
Imagemagick build?
What Imagemagick version are you using?

Does this error hint anything?

I usually use eww to open few work internal websites which are
autogenerated with an SVG plot and a huge HTML table. I have seen
those pages to open fine on emacs -Q but fail to load *sometimes* on
my emacs with my config loaded.

It just happens that yesterday I tried opening braveclojure.com in eww
and it froze my emacs and so I sent that email to emacs-devel. I
simply assumed that it will open fine on emacs -Q. But now we know
that it froze my emacs -Q too. I have consistently been able to freeze
emacs -Q (built with Imagemagick) when I open that braveclojure.com
site on eww.
