In the current trunk,

`M-x eww http://www.nrk.no/ytring/fremtiden-bygges-ikke-med-asfalt-1.12590339'

will crash Emacs, or, if run under gdb, go into an infloop saying
"Maximum string size exceeded", blinking in error, which can't be
stopped from gdb.

These crashes started happening when I updated Emacs a few days ago, and
seem to be related to network traffic.

addr2line gives me the following. I confirmed that disabling svg support
makes the crash go away.

Probably because all this starts from image.c trying to report some
SVG "size error":

Can you show the details of the error message?

Btw, after making this change, I see a lot of error messages from Glib
(called by librsvg), like this:

  (emacs.exe:1624): GLib-CRITICAL **: g_error_free: assertion 'error != NULL' failed

(And, of course, a lot of "Invalid image size" errors in *Messages*.)

Thanks; that fixes the problem for me, too.

How about using g_clear_error to avoid this kind of g_error_free usage?
The function has been there since glib 2.0, so there shouldn't be a
compatibility issue.

gtkutil.c has similar code reusing GError variable, which could be
simplified as well.
