Steps to reproduce (assuming you have a copy of a mtn db laying 
around):

$ mtn co -d monotone.mtn net.venge.monotone mtn
$ cd mtn
$ chmod 100 NEWS
$ mtn status
mtn: fatal: Botan::Stream_IO_Error: Botan: I/O error: 
DataSource_Stream: Failure opening NEWS
mtn: this is almost certainly a bug in monotone.
mtn: please send this error message, the output of 'mtn version 
--full',
mtn: and a description of what you were doing to 
monotone-devel@nongnu.org.
mtn: wrote debugging log to /Users/tommyd/mtn/_MTN/debug
mtn: if reporting a bug, please include this file

We certainly should just ignore unreadable files in the workspace 
and print out a warning at most.
