Status changed to 'Confirmed' because the bug affects multiple users.

[Daniel Leidert (dleidert-deactivatedaccount)]

When does the segfault appear? Just when opening the HTML file? If yes, can you please send me this file? Or are there other steps necessary to reproduce the issue and if yes, which?

this looks similar to https://bugzilla.gnome.org/show_bug.cgi?id=689210

this is a difficult to debug problem, I have not been able to reproduce it. A full backtrace with all debugging symbols available would be very welcome.
