Subject: [Evolution] 3.12.3 crashes in mail_display_plugin_widget_resize()

I'm seeing several of these crashes a day:

Program received signal SIGSEGV, Segmentation fault.
0x00007fffcdbd360c in mail_display_plugin_widget_resize (
    widget=0x7ffee84964d0, dummy=<optimized out>, display=0x2d32460)
    at e-mail-display.c:364
364             if (!WEBKIT_DOM_IS_ELEMENT (parent_element)) {
(gdb) p *parent_element
$6 = {parent_instance = {parent_instance = {parentInstance = {
        g_type_instance = {g_class = 0x3}, ref_count = 77229872, 
        qdata = 0x7ffff1c1eaa0 <soup_buffer_free>}, coreObject = 0x2}}}

(a few full stack traces are below)

It seems that the object at *parent_element is getting smashed.  It
happens when using Ctrl-I (Load Images), but doesn't always happen on a
particular message, i.e. after restarting the message it just crashed on
will load images fine.

Does this look like a known problem?  I don't have the expertise to
debug it, but I'd be glad to work with somebody, or take suggestions for
other information that would be useful to gather.
