Fix crash when mounting with older gvfs

Hi,

Using ubuntu Intrepid with GVFS 1.0, I have no problem mounting shares. With gvfs 0.2.5 (shipped in Ubuntu Hardy), I get a segfault, with this backtrace:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0xb739f720 (LWP 26646)]
0x080546fd in mount_ready_cb (location=0x80a19b0, res=0x8427db0, backend=0x80a1c00) at backendgvfs.c:463
463			g_signal_emit(backend, signals[OPERATION_FAILED], 0, msg, error->message);
(gdb) print error
$1 = (GError *) 0x0


The attached patch fixes it.
