When debugging some programs, if you open Signal View, the debugger backend crashes (Segmentation fault).

The reason is in gdbmi_backend.c, GDBCLIListSignals(), we do the following:
for (MIListSet(signals); ((sig = (MISignalInfo *)MIListGet(signals)) != NULL); ) {
		s = NewSignalInfo();
		s->name = strdup(sig->name);
		s->pass = sig->pass;
		s->print = sig->print;
		s->desc = strdup(sig->desc);
		AddToList(e->dbg_event_u.list, s);
	}

For some signals, its desc is null, and this caused the Segmentation fault.
