ui/dbus: fix buffer-overflow detected by ASAN

Browse Source 
On the last added dbus patch, I left a tiny BO:

==441487==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x611000025a70 at pc 0x7f0817bb764c bp 0x7ffde672ae60 sp 0x7ffde672ae58
WRITE of size 8 at 0x611000025a70 thread T0
    #0 0x7f0817bb764b in dbus_vc_class_init ../ui/dbus.c:401

A cookie for ASAN! not you C :)
