User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en; rv:1.9) Gecko/20080528 Epiphany/2.22
Build Identifier: Mozilla/5.0 (X11; U; Linux x86_64; en; rv:1.9) Gecko/20080528 Epiphany/2.22

The browser crashes when I try to enlarge the fonts.

I reported this to the Epiphany devs, but they determined that it is a bug in the Xulrunner component, so they asked me to report it here.  I tried to reproduce it with Firefox, but it doesn't actually crash.

This is the bug I reported:
http://bugzilla.gnome.org/show_bug.cgi?id=544361
It's been said to be a duplicate of this other bug:
http://bugzilla.gnome.org/show_bug.cgi?id=543589

Reproducible: Always

More info from the core file.  I installed a newer Xulrunner package (from debian Unstable), and got a new core file.  Additionally, the "this" object is displayed below.

The stack trace looks suspiciously similar to the one in bug 444894. (Compare frame 6 and below from comment #1 to frame 1 and below in bug 444894, comment #1)

FWIW I can reproduce the crashes in the website mentioned in #444894 and #444916 too.
