Dear Maintainer,

Iceweasel crashes suddenly on random websites. If a website crashes Iceweasel,
it will crash it everytime it gets visited. Repeatable 100%.

Running it in the console, I get the following output, where it crashes on the
last two lines:

$ iceweasel --safe-mode

(process:25206): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size
== 0' failed
console.error:
  [CustomizableUI]
  Custom widget with id loop-button does not return a valid node
console.error:
  [CustomizableUI]
  Custom widget with id loop-button does not return a valid node
ATTENTION: default value of option force_s3tc_enable overridden by environment.
intel_do_flush_locked failed: Input/output error

I have tried moving ~/.mozilla/firefox and the same issue occurs.

I tried installing iceweasel-dbg and running it through gdb, but when I try to
get a backtrace, I get no stack.

Hello Michael,

which websites provoke such crashes?

What excately do you have done?

You should do something like

  (gdb) thread apply all bt

Please note also https://wiki.debian.org/HowToGetABacktrace

Without further information we can't readjust such situations. Please
provide some more informations.

Regards
Carsten

www.youtube.com is doing it currently, although it's worked in the past.
Maybe their page has since changed in such a way as to trigger this.
There's been many other sites as well, but I haven't recorded them. I'll
see if I can report them in the future for you, if it would help.

Ok, so I've managed to get a backtrace after breaking at exit. I've
attached the output. Hopefully this will be of some use.
