Preamble:
I found this weird bug while debugging a lgob [1] (gobject libs lua bindings)
module for vte.
At first I opened a bug report on lgob BTS [2], then when found that it was
probably a vte3 bug (not sure), also on the gnome BTS [3].
I'm opening an issue also here cause for the moment upstream does not
confirm the bug, and i need some other confirmations
(lgob developer confirms this on a arch machine too).

Description:
Compiling and executing the attached C source file vte.c
( head -n1 vte.c | tr -d "/*" | sh && ./a.out) cause a
floating point exception when no canberra-gtk-module is loaded.

Gnome users does not notice this, cause the canberra gtk module is loaded
by default in a gnome session.

For a quick test try:

$ xinit ./a.out -- :1 # should fail
$ GTK_MODULES=canberra-gtk-module xinit ./a.out -- :1 # should work

Additional info:
* package version(s) vte3 0.30.x

Steps to reproduce:
$ ./a.out
Floating point exception
