>Description:
	I was doing a grep for a string in an inn-2.2 source tree with object
	and programm files and got a: panic:

panic: amap_unadd: nothing there
Stopped in grep at      _Debuggger+0x4: leave

>How-To-Repeat:
	Do a 'grep xxxxx */*' in a place where you have subdirs with binary
	files and watch the panic.
	I can repeat that on my system.
