What if you execute "bro -f '' ..." (which manually sets the filter to  
capture all packets)?

How about '-f "port telnet or tcp port 513"'?

Finally, without specifying the -f flag, what's the output if you print  
capture_filter in event bro_init()? Adding the following piece of code  
(to login.bro) will do:

event bro_init()
	print fmt("%s", capture_filter);
