Comment # 2 on bug 11553 from Mikael Kanstrup

I reproduced this on master while investigating bug 12263. The problem is that
update_cb of scan_local_interfaces recursively callbacks via UI events into
itself. Backtrace below:

(gdb) b ui/iface_lists.c:85
Breakpoint 1 at 0x50e5e0: file iface_lists.c, line 85.
(gdb) s
The program is not being run.
