Here you go:
(gdb) bt full

element = (
const gchar *) 0x19 <Error reading address 0x19: Bad address>
start = (const gchar *) 0x4108cf "last.tsc"
end = (const gchar *) 0x8 <Error reading address 0x8: Bad

result = (GString *) 0x906ae0
separator_len = 1
is_first = 0

single_element = (const gchar *) 0x0
next_element = (

where
1328 gchar *filename = g_build_path ("/", home, "last.tsc");
(gdb) p home
$1 = (gchar *) 0x59d540 "/home/sean/.tsclient"
This looks like a varargs issue. I am getting a non-null returned from
1497 next_element = va_arg (*args, gchar *);
after the "last.tsc":
(gdb) p next_element
$9 = (const gchar *) 0x19 <Error reading address 0x19: Bad address>
